In this paper, three types of air guide vanes are designed: directtype, Ltype, and logarithmic spiral type, respectively. ANSYSFLUENT is used to numerically simulate the internal flow field of turbo air classifier by novel different structures. The numerical results show that the guide vane structures have a good effect on the flow field stability of the annular function zone in the ...
