A model is presented for flow of grinding fluid through the grinding zone. It was found that the flow rate through the contact zone between the wheel and the workpiece is a function of fluid pressure in the grinding zone, delivery flow rate, fluid density, and wheel velocity. An empirical coefficient of value less than 1 is introduced. The coefficient depends on wheel geometry, jet velocity, abrasive property, and fluid property. Air flow interfering with the delivery grinding fluid is also analyzed. A relationship was found between atmospheric pressure and the retention of fluid particles in the boundary layer on the wheel periphery. The model was tested for both porous and impervious wheels.
