Summary

We present a new attempt by means of the generalized boundary element approach to solve an unsteady-state problem of viscous fluid flow. This approach is based on the well-known Fractional Step (FS) scheme which is one of the time splitting techniques. The fundamental equations are split into the advection-diffusion-type equation and the linear Euler-type ones. The advection-diffusion-type equation is transformed into the integral representation with the fundamental solution for the Laplace operator. The Poisson equation which is derived by applying some manipulations to the Euler-type equations is also solved by using the generalized boundary element method. Numerical results of the driven cavity flow demonstrate the accuracy and applicability of our method.
