Abstract: In grinding process, a small amount of grinding fluid can be injected into the contact area for cooling and lubrication. This leads to decrease of the grinding fluid utilisation efficiency and workpiece surface integrity. Based on fluid mechanics theory, a mathematical model of two-phase flow field is established and the simulation of the grinding fluid jet is carried out by FLUENT. The distribution of grinding fluid and the pressure variation curve of the jet process are obtained. The results show that less utilisation efficiency of the grinding fluid in contact area is a combined effect of high pressure airflow, severe backflow and large pressure difference. The utilisation efficiency of the grinding fluid can be improved when jet occurs at the middle position with higher velocity. In addition, in the grinding experiment of surface roughness, the suitable supply parameters are proved by analysing Ra values of the parts.
