Abstract

Flow separation control by electromagnetic field was studied for a flat plate at high angles of incidence. Lorentz force was used as the model for the electromagnetic field and incorporated within a compressible Navier-Stokes flow solver. The compressible solver is based on an implicit, high resolution, and Total Variation Diminishing (TVD) scheme. The computational results were qualitatively compared with experimental observations. For a range of incidence angles, the electromagnetic field has completely prohibited flow separation and enhanced lift coefficient. However, the overall drag coefficient has been slightly increased due to the increase in skin friction.

 

Keywords: Electromagnetic Field – Lorentz Force – Flow Separation – Navier-Stokes – TVD Schemes.
