AbstractNowadays there are various methods for controlling flow separation and its undesirableeffects For this reason in this project numerical modeling of incompressible flow with amach number 0 2 is considered and the control of undesirable flow separation for a turbulentflow is investigated The focus is on flow control by Lorentz forces generated byelectromagnetic fields This force is appeared as a source term in the numerical procedure ofsolving the governing fluid flow equation Finally effects of the Lorentz force on the flowfieldis analysed Numerical solution indicate that using Lorentze force may postpone or eliminateflow separation over aerofoils hence hydrodynamic performance may be increased Initialstudy for the flow separation over a flat plate indicate that flow sepration can be completelyremoved using electromagnetic forces Comprehensive investigation for NACA0015 indicatesaerofoil at different incidence angles the same effects In addition by applying the control bythe Lorentz force Lift coefficient has been increased and drag coefficient was also decreased Thus the stall angle has favourably increased
