Variational method for solving problems of nonsteady-state heat conductivity
Abstract
A variational equation of nonsteady-state heat conductivity (nonsteady-state temperature fields) is obtained for a body of revolution, taking account of the temperature dependence of the thermophysical properties of the material. The finite element method is used to solve this heat equation for the case of axisymmetric convective heat transfer.
