A three-dimensional problem of viscous fluid filtration in domain containing homogeneous porous medium is considered. Filtration flow is described by Darcy-Brinkman law. The boundary of the medium is divided into parts with either no-leak condition or condition on velocity vector flux or pressure. Integral representation for velocity and pressure of fluid is constructed with methods of potential theory. System of integral equations satisfying boundary conditions is solved numerically with piecewise-constant approximation and collocation method. The numerical scheme is tested on problems with different boundary conditions. The effect of viscosity on the flow is also studied. The tests demonstrate high accuracy of numerical method.
