Instability of three dimensional electrically conducting fluid of magnetohydrodynamics Couette flow

摘要: In this work, we consider a disturbed electrically conductive fluid between two parallel planes and study the stability of after applying uniform magnetic field on it. We obtain modified form Orr-Sommerfeld system equation then use QZ (Qualitat Zuverlassigkeit) technique to neutral curves. investigate critical Reynolds numbers for large domain Hartmann Number. Next show that particular values oblique angle, Couette flow destabilizes in some range field. also area changes with change number, number wave number. find instability region has conic type shape. It is found provides stabilizing impact flow, extent demonstrated numbers. From numerical simulations, it observed specific magnitude stabilizes flow.
