in this paper, the combined effect of suspended (fine dust) particles and rotation on the onset of thermosolutal convection in an elastico-viscous fluid in a porous medium is studied. for the porous medium, the brinkman model is employed and rivlin-ericksen model is used to characterize viscoelastic fluid. by applying normal mode analysis method, the dispersion relation has been derived and sol...

The instability of the plane interface separating the two uniforms, superposed, electrically conducting and counter streaming elastico-viscous fluids through a porous medium is examined for visco-elastic polymer solutions in the presence of a horizontal magnetic field and also in the presence and absence of surface tension. These solutions are known as Walters’ (model B  ) fluiare approximated...

The recent development of algebraic explicit stress models (AESM) for viscoelastic fluids rests upon a general equilibrium assumption, by invoking a slow variation condition on the evolution of the viscoelastic anisotropy tensor (the normalized de-viatoric part of the extra-stress tensor [G.
