Investigation for convective heat transfer on grinding work-piece surface subjected to an impinging jet

► Illustrate flow and heat transfer features in vicinity of a grinding wheel. ► Assess heat transfer enhancement of the mist/air jet impingement. ► Swirl flow over rotating disk affects the wall jet flow structure of oblique impinging jet. ► Heat transfer is enhanced near grinding zone if jet direction is reasonable. ► Mist/air ratio and rotational speed are important factors affecting heat transfer in vicinity of grinding wheel.
