Biography
I received my PhD at Department of Thermal Engineering, Tsinghua Uni. in 2002 . In 2014, I finished my h abilitation in t hermo fluid d ynamics at Hamburg University of Technology. My teaching and research interests cover broadly fluid mechanics, heat /mass transfer chemical reaction, and thermodynamics. Through my research, I proposed t he ?pore scale prevalence hypothesis (PSPH)? for turbulence in porous media; the ?parameter extension simulation (PES)? method for simulating turbulent flows; and the ?exergy transformation number? for assessing losses in gas turbines. In 2017 I was award ed the title of ?DFG Heisenberg Fellow for my research in fluid mechanics.
