Velocity calculation scheme in the 2D computatioi vortex-in-cell method applied to the simulation of the laminar boundary layer

The new velocity calculation scheme in the Vortexin-Cell (VC) method is proposed. Within eai step three different kinds of mechanisms: convection, diffusion and vorticity creation at bounda: treated separately. The proposed scheme named as a Vorticity Splitting Method (VSM) and its mz consist in separately consideration of velocities partial derivatives, which are included in the v( Moreover Multi-Time-Step simulation is used in the numerical algorithm because the difference rates of convection and diffusion processes. Direct Numerical Simulation of the laminar boundai on a flat plate in a wide range of Reynolds numbers is used for a test purpose. Velocity profiles о with the ordinary and new schemes are compared to Blasius solution and results of other author: scheme is allowed results obtaining with sufficient accuracy in the wide range of Reynolds numl
