Abstract


In this paper, the linear stability of a saturated rotating porous layer of viscoelastic fluid which is heated from below has been studied. The modified Darcy Law is used to explain the fluid motion. The linear stability theory is employed to find the critical condition of the onset of convective motion. It has been observed that the critical Rayleigh-Darcy number increases with increasing Taylor-Darcy number. In limiting cases, some previous results for viscoelastic fluids in the absence of rotation are recovered from our results.
