  • Jet heat transfer in the vicinity of a rotating grinding wheel

    During grinding, heat is generated by the grains of the wheel cutting the workpiece as they pass at high speeds in the grinding zone. According to Rowe et al. [2], individual grains are responsible for localized and intense heat generation, resulting in short duration spike temperatures at the workpiece sur-face.
