This paper is concerned with a boundary element analysis of two-dimensional transient heat conduction problems. The time derivative in the differential equation is approximated by the time-stepping scheme. The reduced differential equation is transformed into a regularized boundary integral equation which involves no integrals to be evaluated in the Cauchy principal value sense. A new computer code is then developed and applied to several sample problems. It is revealed that there is a suitable value of the diffusion number for each problem to be investigated. The solution procedure is then applied to other two-dimensional problems, after the computational conditions are estimated by the properties obtained in the previous example computations. An accurate numerical solution can be obtained through this process.
