Racing Car CFD

Computational Fluid Dynamics (CFD) tools were applied by an FYDP project supervised by Prof. Zhang to study the aerodynamics of a generic LMP racing car model. The CFD support was provided by AAF's engineer to train and advise the students on their CFD activities.

Particle Image Velocimetry

PIV is an effective non-intrusive flow measurement technique used in wind tunnel testing. AAF recently performed some PIV to enlighten students on the complex fluid structures formed behind a circular cylinder in the large low-speed wind tunnel.

Preliminary CFD of HKUST Campus

AAF performed a preliminary CFD of the HKUST campus area. This demonstration case was performed on the HKUST HPC system. The simulation was performed using the OpenFOAM CFD suite. 

The computational grid was developed using Geographic Information System (GIS) databases of the building and local terrain. The computational domain extends a region of 2 km by 1.5 km. The domain height ranged by 530 m to cover the local mountainous terrain, as well as a sufficient portion of the local atmosphere. 

The results plotted in this demonstrate the preliminary flow field of Category 5 hurricane-force winds coming from the East.

Small-Scale UAV Propeller Wind Tunnel Testing

One of the research groups at HKUST is using the low-speed wind tunnel facility to investigate the aerodynamic performance of commercial propellers. The research group is also working on developing custom-designed blades optimized for low-noise and maximum aerodynamic performance.
