School of Engineering Department of Mechanical and Aerospace Engineering 157 High-order Numerical Method for Predicting Flows over Aircrafts Supervisor: FU Lin / MAE Student: TSE Ming Hang Henry / AE Course: UROP1100, Spring RAE2822 airfoil is a transonic airfoil designed to reduce the effect of shock waves. The report covered extensively steps to produce an analysis of the RAE2822 airfoil and a comparison with experimental data was made. Open-source programs OpenFOAM and ParaView were used for the study. From setting up the software to creating an analysis case, it was not as easy as following the instructions, there were commands to be understood and modifications were made. Using a tutorial case as a reference and online resources, RAE2822 was created digitally for analysis. Although the simulation result might not be identical to the experimental result, potential reasons were suggested. High-order Numerical Method for Predicting Flows over Aircrafts Supervisor: FU Lin / MAE Student: ZHANG Rushan / AE Course: UROP1100, Fall This project consists of 2 stages. The first stage is to use a computer program written by Doctor Cheng Cheng to analyse NACA 0012 airfoil. With the results from the program, the lift curve and the drag polar were generated, and were used to compare with reference data collected under similar parameter settings. The second stage is to draw the mesh for a three-element high-lift airfoil, McDonnell Douglas 30P30N airfoil. In this stage, two types of mesh were generated. The first one is a hybrid mesh, which consists of both rectangular regions and quadrilateral regions. The second one is a structured mesh, which consists only of quadrilateral regions. Extended Ortho-K Lens for Myopics Supervisor: LAM David Chuen Chun / MAE Student: SEO Minji / AE Course: UROP2100, Fall UROP3100, Spring Lack of understanding on corneal response to orthokeratology lens led to a low predictability of the lens efficacy. Ratio of intraocular pressure (IOP) to corneal stiffness was identified as a new factor that influences corneal regression rate after the lens wear. It is hypothesized that cornea with the higher ratio is likely to have less shaping effect and to regress at a faster rate. Ex-vivo porcine eyes (n=??) under 3 designated IOP (5, 15, and 30mmHg) were used to examine the hypothesis. Corneal topography and stiffness were measured before and after the lens wear to monitor the corneal biomechanical changes.
