From the view of fluid mechanics,the shear-free air water interface corresponds to a slip boundary condition in fluid and relatives to the concept of effective slip length.In this paper,the simulation of drag reduction with superhydrophobic surface was done with computational fluid dynamics method by introducing slip boundary condition of velocity.The results of simulation indicated that the dimensionless pressure drop reduction was up to 19.2%.Read More
