Abstract

In the paper the Dual Reciprocity BEM with the modified approximation functions is used to obtain velocity field which can be then utilized when solving convection- diffusion equation. Velocity-pressure formulation (primitive variables) is consid- ered. Solution of the Navier-Stokes equation for incompressible fluid is achieved iteratively. For a given pressure field, velocity distribution is calculated within the domain. In next step pressure field is updated in accordance to the differential equation derived from the continuity condition. 1 Introduction Heat convection is an example of coupled boundary value problem. Determining temper- ature field one has to solve
