Abstract

Boundary-Domain Integral Method is applied for the solution of incom- pressible turbulent fluid flow. The standard two-equation near-wall k - c turbulence model is applied. Integral representations are derived for flow kinematics and flow kinetic transport equations. A special iterative algo- rithm is applied for solving the k and e nonlinear transport equations and the resulting set of averaged Navier-Stokes equations. Effect of buoyancy force on production of turbulence is accounted for. The numerical results for side-heated quadratic enclosure are presented for a Prandtl number equal to 0.71 with the Rayleigh number values 10® and 2 * 10®. 1 Introduction The paper deals with the numerical simulation of a turbulent fluid flow using the Boundary-Domain Integral Method (BDIM). A time-averaged form of the Navier-Stokes equations formulated for the velo
