| Abstract: | According to the characteristics of ellipse, this paper derives the equation of heat trans- ferred through wall of elliptic cylinder and the temperature distribution in the wall. It presents the relation between heat transfer characteristics of elliptic cylinder and geometry parameters of ellipse, and the heat transfer coefficient as well. Besides, the paper discusses the maximum heat transfer and critical heat insulation thick. At last, the limits of the parameters in which the heat transfer passed through the wall of elliptic cylinder treated as that passed through a cylinder wall is found out. |
