Abstract

Combination of magnetic field and internal heat generation effects on double-diffusive convection in nanofluids layer is applied in the existence of Soret and Dufour effects. The model employed for the nanofluids as- sociates with the Brownian motion and thermophoresis. Linear stability theory upon normal mode technique is used and the eigenvalue solution is obtained by using the Galerkin technique. On the stationary convection, it is observed that the application of magnetic field stabilizes the system while internal heat generation destabilizes the system. The analysis also reveals that it is possible to delay the onset of convection through nanofluids parameters in the system. [ABSTRACT FROM AUTHOR]

Abstract

The influence of coriolis force on the onset of steady Rayleigh-Benard convection subjected to Soret parameter in a horizontal nanofluid layer is considered analytically. The confined lower and upper boundary conditions of the nanofluid layer are considered to be free-free, rigid-free and rigid-rigid respectively. The model used for the nanofluid incorporates the effects of Brownian motion and thermophoresis diffusion. Following the usual linear stability theory, the eigenvalue solution is obtained numerically by using Galerkin technique. From the investigation, the presence of coriolis force due to the rotation inhibits the onset of convection in nanofluid layer and have a stabilizing effect. Further, the instability of the system get advanced with the increased values of the Soret parameter. [ABSTRACT FROM AUTHOR]
