Thermal convection in a Walters' (model B') elastico-viscous dusty fluid in hydromagnetics with the effect of compressibility and rotation

51-62

A compressible, electrically conducting Walters'B' elastico-viscous fluid heated from below in the presence of a magnetic field and rotation is considered. At stationary convection, Walters' (Model B') elastico-viscous fluid behaves like a Newtonian fluid and compressibility, rotation are found to have a stabilizing effect whereas the suspended particles have a destabilizing effect on the thermal convection and magnetic field has a stabilizing effect under certain conditions. The presence of magnetic field and rotation introduces oscillatory modes in the system which were non-existent in their absence. Graphs have also been plotted by giving some numerical values to the parameters.

Simulation of thermal convection depending on the angle between gravity force and temperature gradient

In this papers the influence of the angle between the gravity force and the temperature gradient on the convection process is studied and simulated. Free convection is the kind of heat transfer in which the fluid's motion is caused by the volume forces, usually by the gravity force but also due to centrifugal forces or magnetic field's forces. The differences of temperature around the body are connected to differences of density and consequently buoyant force appears. For that reason, in the equations of motion the volume force is substituted by the expression representing the difference in specific weight and bouyancy which is proportional to the difference of density. It is a very common phenomenon that the convection appears in the film of fluid between the surfaces of two different temperatures
