CONSTRUCTION OF A VARIATIONAL FORMULATION FOR HEAT TRANSFER

ABSTRACT
This paper gives two useful methods to construct a variational formulation for heat transfer. Xu's variational principle for heat transfer in terms of entransy is used as an example to elucidate how to correct a wrong variational formulation, and the semi-inverse method is adopted to establish a needed variational principle.
