Research Status
Prof. HE Feng engages in both basic and applied research in fluid mechanics and related fields. Prof. He has conducted numerical simulation and laboratory experiments to investigate flow phenomena including but are not limited to micro fluidics, vortex dynamics, compressible shear layer, optimization design, numerical simulation, qualitative and quantitative visualization.
Currently Prof. HE is mainly interested in understanding flow structure, shocklet and turbulent characteristics in compressible mixing layer through theory-computation-experiment interaction approach. Compressible mixing layer is basic flow for scramjet, also typical flow for compressible turbulent analysis. She is also generally interested in understanding wing tip vortex, supersonic jet, hypersonic boundary layer receptivity.
