| Abstract: | Contact melting processes of phase change materials (PCMs) inside a horizontal elliptical tube are analysed. According to the law of ploting ellipse. the ellipse is approximately constructed by several circular arcs. Then the heat transfer and motion of the liquid melted in contact region are analysed by film theory. The melting velocity. melting rate of the solid and ayerage Nusselt number are obtained. and the effects on these parameters are discussed. The results include that for melting inside a horizontal cylindrical tube. |
