Abstract：The internal flow field in suck cavity of a turbulence mill was calculated numerically using a 3-D steady turbulence flow calculation by Numeca, a 3-D viscous flow software. Based on the computational results, pressure and velocity distribution was analyzed, and some flow patterns were discussed. It could also be applied to the future whole machine simulation.
