Investigation on cooling behavior of axially rotating heat pipe in profile grinding of turbine blade slots

During profile grinding of fir-tree blade slots, a key issue is usually the excessive heat caused by the complex contact zone. Most studies have focused on the cooling efficiency of the coolant; however only few have investigated the heat transfer potency of the grinding wheel matrix. In this study, a new cooling method that incorporates an axially rotating heat pipe (RHP) in the profile grinding wheel has been proposed. The cooling behavior of …
