ABSTRACT
In this paper an expontial finite-difference scheme, first presented by Bhattacharya for one-dimensional, unsteady heat conduction problems in a plane wail, is used to solve various partial differential equations. Solutions of the unsteady diffusion equation in three dimensions and of the viscous form of Burgers’ equation ere used to illustrate the method. Predicted results are compared with exact solutions or with results obtained by other numerical methods.
