Abstract
This paper represents a boundary element formulation for steady and un steady slow viscous flow of incompressible Newtonian fluid. The steady flow completely ignores the inertial effect, while the unsteady flow retains the local acceleration term. The boundary integral equations a nd fundamental solutions are presented in two and three dimensions. A Laplace transform and numerical inversion approach is used for the uns teady problem. Two-dimensional internal flow problems are solved to il lustrate the capability of the developed algorithms.
