%X This paper makes a numerical simulation of the flowing characteristics and sampling efficiency of the Tubular Sand Trap for example in the sand flow structure.In order to make the simulation more truthful,we make the gridding better against the calculation domain,calculate wind field around sand trap,and analyze the effect of the gridding division to the calculation results.Through the analysis of the calculation results,we discuss the influence of different membrane permeabilities to wind field flowing and...
