Simulation on Heat Exchange Performance of Heat Pipe Grinding Wheel

A three dimension heat transfer model, using a commercial code Fluent software which was based on FEM, was developed to describe the grinding process of heat pipe grinding wheel in this paper. Temperature field of heat pipe grinding wheel was analyzed by this model to identify the effects of different conditions on the temperature of the work surface of grinding wheel including the heat flux of contact zone, cooling parameter and rotation speed of grinding wheel. The heat exchange performance of heat pipe grinding wheel also was studied based on the temperature of the work surface of grinding wheel. Model calculations showed that the high heat flux and unsatisfactory cooling capacity could cause a high temperature of the work surface of grinding wheel as well as the temperature of the work surface of grinding wheel was not affected by the rotation speed of grinding wheel. A significant amount of the input heat could be taken away from the heat pipe grinding wheel.
