My research is funded by the National Natural Science Foundation of China, Guangdong-Hong Kong-Macau Joint Laboratory for Data-Driven Fluid Mechanics and Engineering Applications, and the Southern University of Science and Technology. I am very grateful for their support.

Research Facilities

My research group has access to the TianHe-2A cluster, located at the National Supercomputer Center in Guangzhou, as well as the Tai-Yi supercomputer on campus. Both are P-scale machines and support our computational investigation of multi-physics and multi-scale problems. My lab is equipped with ThinkStation P920/P620 tower workstations for methodology development.

Research Sampling

Patient-specific cardiovascular simulations

This pulmonary model is built from a healthy 20 month old male, consisting of 772 outlets and 6 Strahler orders. The simulation is performed with a boundary layer mesh with 26 million linear elements. The model is prepared by Ms. M. Dong and the mesh is prepared by Dr. W. Yang from Stanford.

FDA benchmark

The US Food and Drug Administration (FDA) introduces a set of benchmark problems for CFD code validation. The PERIGEE code has been tested at Reynolds numbers 500, 3500, and 5000 using a mesh of 28 million linear tetrahedral elements. The numerical results match well with the experimental results. The following figure shows a snapshot of the flow field at Reynolds number 500 (top), 3500 (middle), and 5000 (bottom).

Boiling

Boiling is a complex phase transition phenomenon. It involves complex fluid flows, various instability phenomena, and liquid-vapor phase change. We have developed a suite of novel theoretical and numerical methodologies for the study of boiling. The following figure shows a snapshot of the temperature field in a boiling simulation.
