Numerical simulation of drag reduction of superhydrophobic surface in turbulent channel flow
摘要
Abstract
The turbulent flow in a channel with superhydrophobic surface was studied by numerical-simulation, and the drag of the surface was analyzed. We applied structural grid to grid the field,and VOF model and Realizable k-e turbulent model to make the simulation. It shows that: the wall slip and low turbulent en-erage near the wall are the importment factors 'that make the drag of hydrophobic surface reduced; the volume of the air in the cavity influences the drag of superhydrophobic surface obviously, however, the drag reduction still exit even if the cavity were full of water.关键词
