The development of an unsteady boundary-layer method using a finite difference scheme is presented. Cebeci-Smith zero equations model is implemented and Keller box scheme has been used. A low-pass filtering function is applied to eliminate numerical instability near the wall. Boundary-layer thickness, displacement thickness, velocity profiles and drag coefficient are calculated. Comparisons of this method with analytical models, CFD simulations and experimental data show good agreement

Abstract
The development of an unsteady boundary-layer method using a finite difference scheme is presented. Cebeci-Smith zero equations model is implemented and Keller box scheme has been used. A low-pass filtering function is applied to eliminate numerical instability near the wall. Boundary-layer thickness, displacement thickness, velocity profiles and drag coefficient are calculated. Comparisons of this method with analytical models, CFD simulations and experimental data show good agreementFile in questo prodotto:
