School of Engineering Department of Mechanical and Aerospace Engineering 160 High-order Numerical Method for Predicting Flows Over Aircrafts Supervisor: FU Lin / MAE Student: BHULLAR Jobanpreet Singh / AE Course: UROP 1100, Summer In this comprehensive investigation, we delve into the intricate aerodynamic characteristics of the NACA 4412 airfoil. Our primary focus centres on evaluating key performance metrics, including pressure distribution, lift coefficient, and drag coefficient. These parameters play a pivotal role in understanding the airfoil’s behaviour and optimising its design for various applications. The NACA 4412 airfoil, undergoes rigorous analysis under subsonic flow conditions. Specifically, we consider a Mach number below 0.75 (approximately 260 m/s), ensuring that our findings remain relevant to practical scenarios encountered in aviation. Our methodology involves using a computational fluid dynamics (CFD) software called the SU2. Wireless and Gentle Medical Soft Miniature Robot for Intestine Endoscopy Supervisor: HU Wenqi / MAE Student: ZHANG Yunming / ISD Course: UROP 1100, Summer This project addresses the need for enhanced control and precision in gastrointestinal diagnostics, particularly in the use of the PillCam, a non-invasive tool for inspecting the small intestine. The current challenge with the PillCam is its lack of controllable locomotion, which can result in missed areas or insufficient image capture due to its passive movement through the digestive tract. To overcome this, we propose a novel design using a wireless, soft, miniature robot that employs magnetic soft materials. This robot, driven by an external rotating magnetic field, generates traveling waves along its body to mimic the movement of an earthworm, allowing for controlled navigation within the intestine. The robot was rigorously tested on both rigid tracks and in ex vivo porcine intestines, demonstrating excellent controllability, minimal rolling or twisting, and consistent locomotion under varying conditions. Future developments will focus on further miniaturization to replace the PillCam's shell, integrating imaging capabilities, and conducting comprehensive animal model testing to assess its potential in providing superior diagnostic and therapeutic functions compared to the current PillCam technology. Anti-Glaucoma Eye Mask Supervisor: LAM David Chuen Chun / MAE Student: BIBI Iqra / AE Course: UROP 1100, Summer Myopia is a common eye disorder where affected individuals are able to see close-up objects clearly but not distant objects. By 2050, nearly half of the world population will have myopia. Intraocular pressure (IOP) is the fluid pressure inside of the eye, which is maintained by the production and outflow of fluids in the eye. Studies suggest that high IOP levels are found with increasing myopia. And, hence the exploration of lowering the IOP levels to mitigate myopia is being studied. In my UROP study, I carried out two areas of interest in this field namely investigating the effect of using a IOP lowering device and creating a prototype to take picture of the retina. These will be referred to as Track A and Track B respectively throughput the report.
