Numerical investigation of 3-D separated viscous incompressible fluid flow past an obstacle on a plane. (Russian. English summary) Zbl 1109.76352
Numerical investigations of a liquid flow past near an obstacle given by the equation $$y=ae^{-b(x-x_0)^2 - bz^2}$$ are fulfilled. The liquid is considered as a viscous incompressible and the liquid flow is uniform on the infinity. Equations under investigation are written in a form conservation laws ( for the mass and the momentum) by use of the ”pressure- velocity” variables. Numerical integration of the equations is carried out by the known method of physical variables splitting generalized for the case of arbitrary curvilinear system of coordinates. The topological structures of the 3-D flow arising near a body surface are studied for different Reynolds numbers.
