    Thermomagnetic Convection in a Ferrofluid Layer with Throughflow

    By Savitha B, C. E. Nanjundappa

    Abstract: The effect of vertical throughflow on the onset of thermomagnetic convection in a ferrofluid layer in the presence uniform vertical magnetic field is investigated theoretically. Both the boundaries are considered to be rigid-ferromagnetic and insulated to temperature perturbations. The resulting eigenvalue problem is solved numerically using the Galerkin technique as well as analytically by regular perturbation technique with wave number as a perturbation parameter. Results show that the effect of …

    Effect MFD Viscosity on Bénard–Marangoni Ferroconvection in a Rotating Ferrofluid Layer with Convective Surface Boundary Condition

    By Savitha B, C E Nanjundappa C E

    Abstract: AbstractThe combined effect of Coriolis force due to rotation and magnetic field dependent (MFD) viscosity on the onset of Bénard–Marangoni convection in a horizontal layer of ferrofluid is investigated theoretically. The lower boundary is taken to be rigid–isothermal, while the upper free boundary open to the atmosphere is flat and subject to a convective surface boundary condition. The Galerkin technique is employed to extract the critical stability parameters numerically. It …
