A subdomain boundary element method for high Reynolds laminar flow using stream function-vorticity formulation /
The paper presents a new formulation of the integral boundary element method using subdomain technique. A continuous approximation of the function and the function derivative in the direction normal to the boundary element (further "normal flux") is introduced for solving the general form...

| 520 | |a The paper presents a new formulation of the integral boundary element method using subdomain technique. A continuous approximation of the function and the function derivative in the direction normal to the boundary element (further "normal flux") is introduced for solving the general form of a parabolic diffusion-convective equation. Double nodes for normal flux approximation are used. The gradient continuity is required at the interior subdomain corners where compatibility and equilibrium interface conditions are prescribed. The obtained system matrix with more equations than unknowns is solved using the fast iterative linear least squares based solver. The robustness and stability of the developed formulation is shown on the cases of backward-facing step flow and a square-driven cavity flow up to the Reynolds number value 50 000. | ||
