Rayleigh–Bénard convection in rotating nanofluids layer with feedback control subjected to magnetic field

Abstract

Abstract Magnetic field on Rayleigh–Bénard convective instability in rotating feedback–controlled nanofluids layer heated from below has been examined for the boundaries of free–free, rigid–free and rigid–rigid. Model applied to nanofluids associated with the Brownic movement and thermophoresis mechanism. A normal–mode linear stability assessment has been performed, the eigenvalue solution has been extracted by using single term Galerkin technique and computed by employing Maple software. It is found that the influences of magnetic field, feedback control, rotation are to slow down the thermal instability.
