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.
Flow Visualization Demo
This demonstration illustrates how a laser sheet may be used to visualize a section of the flow field, revealing complex fluid structures formed behind a bluff body.
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.
