Film coefficient heat transfer
WebThe flow regime of condensate in liquid film is referred by Re. It is in laminar flow when Re < 400, which was introduced before. Within the laminar region, the flow of condensate … WebIn film boiling, heat flux causes a film of vapor to cover the surface fully. This significantly reduces the convection coefficient. Film boiling occurs when the pressure of a system drops or the flow decreases. In this case, …
