Bifurcation and Oscillation Effects of Gyrotactic Swimming Microorganism Suspension in Vertical Pipe

Imperial College London MS.c Individual Project * 📍Imperial College London 🇬🇧 📅 05/2020-10/2020 👨‍🏫supervised by Prof. Yongyun Hwang and Dr. Lloyd Fung Individual MATLAB Abstract The term “Gyrotactic” represents the swimming behaviour of certain types of microorganisms in suspension subjected to gravity and shear torque. The interesting collective behaviour is shown in the vertical pipe flow, that is, the cells swim toward the centre and the wall in the downward flow and the upward flow, respectively. Instabilities arise from this effect and lead to bifurcations. ...

Optimisation of a Wind Turbine Airfoil Prototype

International Summer school: Experimental Fluid Mechanics Group Project 📍Faculty of Mechanical Engineering, University of Southern Denmark 🇩🇰 📅 8/2018 director & lecturer: Prof. Ivar Lund Key participant of team of 7, in charge of 3D printing, wind tunnel boundary layer velocity profile calibration and conducting experiments Wind tunnel test, PIV Abstract This group project aims to optimize the performance of a wind turbine airfoil prototype of LM Wind Power through the introduction of effective vortex generators. The primary objectives include enhancing aerodynamic efficiency and increasing power generation potential. The optimization process involves conducting wind tunnel and water channel Particle Image Velocimetry (PIV) tests to analyze the effects of the vortex generators on airflow patterns and lift-to-drag ratios. By carefully analyzing the test results, the project aims to provide valuable insights and recommendations for improving the design and performance of wind turbine airfoils. ...
