25-2-2003 · The introduction of slots in the grinding wheel has beneficial effects on the critical heat flux for burning. It can be seen in figure 5 that the critical heat flux, obtained in simulation tests where the grinding heat flux is provided by an electrically heated element fused when film boiling occurs, increased by approximately 25% when 32 slots were introduced into the wheel (Salter, 1985).
