I’m an engineering PhD candidate from HKU. The main research objective is the aerodynamics in urban environments based on LES, resolving the multi-scale of the tree. Wind tunnel experiments are also conducted to supplement the coupling effect of the UGI and street canyon on the momentum transport. The post-processing of the wake turbulence is focused on the scale recognition based on decomposition methods. I used to investigate the indoor thermal environment and pollutant dispersion during my master’s degree.
