Validation Solution of Incompressible Viscous Flow Over Multi-Element Airfoil

Computation fluid dynamics (CFD) simulations are very important tools, which use algorithms and numerical methods for analyzing and solving problems in fluid mechanics. Computer programs are adopted in order to simulate the interaction between gases and liquids with boundary conditions. The programs have the ability to undertake speedy and accurate simulations of complex scenarios, which include turbulent and transonic flows.This paper aims to study an incompressible, viscous, turbulent flow over multi-element airfoils. The governing equations (NS) are solved by using k-epsilon model and SIMPLE algorithm turbulent, steady-state, incompressible flow using the commercial code ANSYS Fluent. Detailed studies are done at different angle of attack flight conditions. By using kepsilon model and simple algorithm we have obtained the accurateresults; that is successful in comparing with wind tunnel results of NACA23012.
