In the present paper, double-diffusive convection, taking into account Coriolis effects, in a horizontal layer of Brinkman-anisotropic bi-disperse porous medium is analysed. Via linear instability analysis, we find that convection can set through stationary or oscillatory motions and critical Rayleigh numbers for onset secondary flow (steady convection) overstability (oscillatory are determined.

In this paper a second order monotone numerical method is constructed for a singularly perturbed ordinary differential equation with two small parameters affecting the convection and diffusion terms. The monotone operator is combined with a piecewise-uniform Shishkin mesh. An asymptotic error bound in the maximum norm is established theoretically whose error constants are show to be independent...

In this paper deals with the combined effect of thermal radiation and heat source on the MHD free convection heat and mass transfer flow of a viscous incompressible fluid past a uniformly vertical porous plate. The velocity, temperature and concentration field are obtained and discussed graphically for various values of the physical parameters present. In addition, expressions for the skin fric...

A combined experimental and numerical study of the horizontal Bridgman growth of pure succinonitrile (SCN) has been performed. The effect of convection on interface propagation and shape is quantified and discussed. Measurements were obtained both under conditions of no-growth and for a 40 µm/s growth rate. The quantities measured include interface shape and location, melt velocities, and tempe...
