The purpose of this work is to evaluate the suggested analytical expression in determining the melt pool geometry for SLM processes, by considering heat transfer and phase change …
WebT = change in Temp Normal distance (2) = T − ( T + Δ T) Δ x (3) = − Δ T Δ x The temperature gradient is the positive quantity in direction of increasing temperature. Since heat always flows from higher temperature to lower temperature. The temperature gradient along the direction of heat flow has a negative value.
