Abstract
In the present study, validation of discretization of Navier Stokes Equations of the OpenFOAM was investigated. The authors computed a flow over a flat plate by using the OpenFOAM and the result was compared with theoretical solution of the Blasius equation. The computational domain is rectangle, with its height of 0.5m, width of 0.4m, and the distance along the flat plate of 0.3m. The grid number over the plate were 200 X 300. 50 grid points in the x-direction were located upstream of the leading edge of the flat plate. The first gird points above the wall had height of 80 X 10-6m in the y-direction. The free stream Mach number was set at 0.3. The simulated velocity distribution in the boundary layer was well compared with the theoretical one. However unrealistic overshoot the velocity at the edge of the boundary layer was observed. Further investigation is needed for overshoot of the velocity.
