Effects of convection and density difference on contact melting around a cylinder
چکیده انگلیسی

Contact melting around a horizontal cylindrical heat source is investigated theoretically. Considering the convection and solid–liquid density difference, the expression of melting velocity is obtained by solving the dominant equations of the molten layer. The effects of convection and density difference on the contact melting are analyzed and discussed. It is found that convection hinders the heat transfer from the heat source to solid phase change material (PCM) across the molten layer, and smaller melting velocity will be obtained while considering solid–liquid density difference. The comparison of the result in this paper with those of previous study shows the validity of the analytical mode established.
