Abstract

Boundary-Domain Integral Method is applied for the solution of in- compressible turbulent fluid flow. The standard two-equation near- wall k - e turbulence model is applied. Integral representations are derived for flow kinematics and flow kinetic transport equations. 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 ve- locity-vorticity variables is employed through the Reynolds decom- position of the instantaneous value of each field function. Turbulent stress tensor is interpreted in the Boussinesq manner. Two-equation near wall k — e or turbulent kinetic energy - energy dissipation rate model is used. Particular attention is give
