Effect of Coriolis Force and Gravity Modulation on the onset of Double Diffusive Convection in a Weak Electrically Conducting Boussinesq-Stokes Suspensions with Saturated Porous Media
Keywords:Boussinesq-Stokes suspension, Rayleigh-Benard convection, Double diffusive convection, gravity modulation
The effect of gravity modulation along with rotation is analysed in Boussinesq-Stokes suspension in a porous media subjected to double diffusive convection. The study consists of a linear and a non-linear analysis. The thermal Rayleigh number is obtained using a regular perturbation technique. The study suggests that instead of taking electrically non-conducting fluid it is better to consider electrically conducting fluid with weak electrical conductivity as this ensures a stable environment in the presence of a magnetic field. Taylor number is found to stabilize the system. The nonlinear analysis is done using a truncate Fourier series expansion that give rise to a system of Lorenz equations. Nusselt and Sherwood numbers are used to quantify the heat and mass transfer, respectively. Frequency of modulation stabilizes the system which can be controlled to our desire.
