Two-dimensional unsteady heat conduction analysis by improved multiple-reciprocity boundary element method

Author(s): Y. Ochiai & T. Sekiya

Abstract:
If the initial temperature is assumed to be constant, the boundary ele- ment method (BEM) does not need a domain integral in unsteady heat con- duction problems without heat generation.

However, under heat generation or nonuniform initial temperature distribution, the domain integral is necessary.

This paper shows that the two-dimensional problems of un- steady heat conduction with heat generation and initial temperature can approximately be solved without the domain integral by the improved multiple-reciprocity boundary element method.

In this method, the domain integral in the each step is divided into point, line and area integrals. 1 Introduc...
