| Project Supervisor(s) | Dr Bilal Anjum Asst. Prof Najam-us-Saher |
| Project Abstract | The remarkable opto-electronic characteristics offered by perovskite materials having a ABX3 type crystal structure have revolutionized the semi-conductor device fabrication technology and in turn the development of thin films of organic and inorganic perovskite materials has led to the unusually high power conversion efficiencies (PCE) of perovskite solar cells (PSC). The use of these thin film-based PSC has outperformed the conventional polycrystalline silicon based solar cells. However, the PCE’s of PSC gets limited by the inherent defects associated with thin film development process. Various thin film development process includes dip coating, spin coating, electrospinning, immersion precipitation, physical/chemical vapour deposition. Out of the aforementioned methods, spin coating is considered to be the simple yet most efficient method to develop ultra-thin films. Considering the costs of the available spin coaters, one of the objective associated with the project is to design and fabricate a low cost spin coater capable of controlling the coating speed and time with in the range of 500-10,000 rpm and 1-5 min. The initial aspects to address would include design of a vacuum chuck having the provision of stable mounting of the sample glass slide, an air exhaust and a fluid drain system, calculations and selection of appropriate motor, calculations and selection of vacuum pump to satisfy the need of efficient sample gripping, selection of an appropriate sensor to monitor speed and a digital control unit to programme and control the desired spin coating parameters. This would be followed by fabrication process which would involve procurement, fabrication, and assembly. Final aspect related to the assessment of the spin coater would be to develop perovskite thin films and to characterize the film thickness with respect to parameters such as rotational speed, rotational time. |

| Project Supervisor(s) | Dr Bilal Anjum Lec Muhammad Umair Akhtar |
| Access to clean water is a problem being faced globally by every country in one form or another. The progress in industrial technology and the large scale of industrial estates have left our water sources at risk of being contaminated, with every passing day making the problem worse. The past couple of years have seen a peeked interest towards utilization of porous nano-composite membranes for water purification applications. This is because these membranes exhibit substantial amounts of thermal stability, separation efficiency, chemical inertness, and corrosion resistance. The scope of the project is to identify mathematical models which predict the water flow through porous membranes. This would be followed by the application of identified mathematical models governing the water flow through porous membranes to predict the water flow through CNT based membranes and it’s validation through already published literature on experimental results of CNT based porous membranes. Finally, the best suited model would be used to access the experimental results of flow through porous MWCNT/Silver membranes prepared and characterized, in house |

| Project Supervisor(s) | Lec Muhammad Umair Akhtar Dr Hasan Aftab Saeed |
| Project Abstract | The purpose of this research is to analyze the life of a low-pressure steam turbine blade under high cycle fatigue (HCF) during startup operation. The variables to analyze in this research are the steady linear elastic centrifugal stresses to determine the stress stiffening effects, dynamic stresses during unsteady excitation pressures at startup and the varying damping ratio of the blade. The initial phase of the research involves obtaining the mechanical and fatigue properties of the desired material from literature. SN curves are to be analyzed and used to obtain the desired properties. The data is useful for developing finite element model of the blade. This will be followed by Finite Element Modeling and Analysis considering centrifugal stress, excitation pressure and damping ratio as variables. The initial part of this phase involves applying steady linear elastic stresses due to centrifugal forces. The next part is modal analysis which involves studying the vibration characteristics of the blade. This is followed by simulating unsteady flow of steam using appropriate software while considering the varying nature of the excitation pressures during startup and the damping ratio of the blades. Lastly, the project involves developing the fatigue life probabilistic model. This includes using the stress cycle histories obtained from the FEM analysis and discretizing them to stress cycle blocks along with the associated cycles to failure. This is followed by the assessment of the accumulated fatigue damage. |

| Project Title | Design and analysis of high-volume low speed fans |
|---|---|
| Group Members | |
| Project Supervisor(s) | Dr Zafar Abbas Bangash |
| Project Abstract | Technically, an HVLS — high-volume, low-speed — fan is a ceiling fan greater than 7 feet (2.1 meters) in diameter. Unlike a small, high-velocity fan that creates small, turbulent air streams that quickly disperse, an HVLS fan relies on size, not speed, to move a significant amount of air. Originally designed for large spaces such as halls, mosques and factories, HVLS fans have evolved as technology has rapidly improved. They now are found in a wide variety of industrial, commercial and residential spaces, often working in conjunction with HVAC systems for energy savings. Because of their size, HVLS fans are effective and efficient. Using ¾- to 2-hp motors, they consume power at a fraction of the cost of multiple small ceiling fans, and significantly lower noise.
The task is to design a complete HVLS fan (motor, drive mechanism) with a dia of 8-10 ft. system fabrication (mounting of blades on ½ to 3/4hp motor, speed control mechanism). Trial installation and runs should be carried out in a designated hall. Flow measurements in the hall to compare performance to standard fans. (Potential for Industry – Pakistan’s fan industry) |

| Project Supervisor(s) | Dr Khalid Mahmood |
| Project Abstract | Selective laser melting is the branch of additive manufacturing in which parts are made layer by layer using laser beam as a heat or energy source to melt the powder layers and manufacture the part according to the CAD model. It has the ability to manufacture highly complex parts which are very difficult to manufacture using conventional techniques. SLM is very popular technique to manufacture orthopaedic implants for the medical industry. If the human bone is damaged, then orthopaedic implants can be installed as a substitute in the human body to ensure quality life for the person. Implants manufactured using SLM have very high elastic modulus as compared to human bone which can cause stress shielding and damage the human bone and so elastic modulus of the implants needs to be lowered. For this purpose, in this research work, we have designed many implants using gyroid and diamond TPMS structures that have elastic modulus close to the human bone, are biocompatible and have good mechanical properties. All the implant designs were inspected and their results were compared and validated with the existing literature. All the designed implants in this research work meet the requirements of an ideal orthopaedic implant and can be physically installed in the human body. |

| Project Supervisor(s) | Dr Syed Gul Hassan Naqvi |
| Project Abstract | Transportation and automobiles have become a part of our daily lives and the risks associated with them of unwanted collision have also increased with automobiles being manufactured at a very high level all over the world. With the increasing trend of fatalities and injuries caused by the road traffic accidents, making the vehicles safer has become more critical. In the early years vehicle were made of solid metals and heavy frames which provided enough occupant protection but with time the need of making vehicles fuel efficient the low weight requirement has changed the manufacturing era of automobiles. Although we cannot avoid the occurrence of unwanted collisions but the impact and severity of crash can be reduced. Thin Walled Columns are extensively being used in various engineering applications for the purpose of safety requirements due to their high energy absorption capacity. Their primary purpose is to absorb the excess amount of impact energy during an unwanted collision undergoing deformation. Numerical analysis of crushing behavior using Finite Element Module LS-DYNA is carried out to study the best performance parameters which are specific energy absorption (SEA), mean crushing force (MCF) and low peak force (PF) by varying different design variables including cross sectional geometry, thickness and length. The objective is to find the best optimal crash box which undergoes progressive deformation to absorb collision energy for the application in automobiles to enhance the safety for passenger cabin. To study the effect of number of corners on crashworthiness parameters, polygons having 5 to 8 corners are numerically analyzed and the best of them is further numerically investigated with circular, rectangle and square cross sectional shape. Thin walled tube having hexagonal cross section is found to be the best for energy absorption under axial impact loading while comparing selected crashworthiness parameters.

| Project Title | Investigation of Effect of Multiple Stepping and Curvature on Metallic Tubes for Crashworthiness Parameters and Energy Absorption Applications |

| Project Supervisor(s) | Dr Hasan Aftab Saeed |
| Project Abstract | Crashworthiness of the structure is the most crucial concern in modern day automobile and aerospace industry, in order to protect the occupants, payload, sensitive equipment and the environment in case of any fatal crash situation. Light weight, cost effective and efficient thinwalled energy absorbing structures are the optimal choice to serve the purpose with enhanced crashworthiness characteristics while under dynamic crushing. The characteristics of energy absorption are size, cross-sectional geometry, material and boundary condition dependent for thin-walled structures. Thin metallic tubes proved themselves as efficient energy absorbers and have been in extensive use for many aerospace and automotive applications to improve the structure crashworthiness. Crashworthiness parameters may be improved through multi-cells arrangement, multiple cross-sectional features, functional gradient characteristics, addition of triggers and foam or honeycomb filling. Stepping in tube’s structure can provide energy absorption with progressive failure as per a design’s specific requirement; however, geometry parameters may influence their performance capabilities. Another important parameter is curvature of the surfaces or corners which may increase the critical buckling load and may guide buckling initiation and propagation. In this study, stepped tubes sensitivity with geometric variation and curvature effects are investigated on energy absorption characteristics of metallic tubes for circular and square tubes; with and without addition of curvature for square tubes and also with curved multi-cells stiffeners along the radial and axial direction and unconventional arrangements of bi-tubular arrangements with and without curvature. A number of geometry arrangements are studied and the effects of adding stepping and curvature are studied for their deformation and energy absorption characteristics. Different parameters such as mean crushing force, peak crushing force and specific energy absorption are determined and discussed for all of the proposed configurations. The proposed arrangements show a relatively stable crushing behavior and high crush force efficiency. In the final part, a robust decision making technique.
The COmplex PRoportional ASsessment (COPRAS) is applied to the proposed configurations for determination of curvature effects in order to find the best configuration which is based on the amount of energy absorbed, low crushing force and high crush force efficiency.
