Abstract:
By using hydrodynamic and thermal modelling, the variation of the convection
heat transfer coefficient (CHTC) of the process fluids within the grinding zone
has been investigated. Experimental measurements of CHTC for different grinding
fluids have been undertaken and show that the CHTC depends on the grinding wheel
speed and the fluid film thickness within the contact zone. The film thickness
is determined by grinding wheel speed, porosity, grain size, fluid type, flow
rate and nozzle size. The CHTC values are compared for a wide range of grinding
regimes, including HEDG, creep feed and finish grinding.
