| Abstract: | Contact melting around a heat source with non-isothermal wall is investigated.A theoretical model for contact melting around a horizontal cylindrical heat source,whose wall temperature varied with angle,is established.Condition of heat transfer and motion of the liquid molten in contact region are studied.Control equations of melting are established with Nusslet’s liquid film theory.And analytical solution of melting velocity is obtained theoretically.It includes result published in literature about melting around the heat source with constant temperature.Melting velocity,thickness and pressure distribution of molten layer under different melting conditions are studied.Effects of temperature distribution on melting are obtained. |
