Chaotic convection in couple stress liquid saturated porous layer‎

‎In this paper‎, ‎we have investigated the chaotic behavior of thermal convection in couple stress liquid saturated porous layer subject to gravity‎, ‎heated from below and cooled from above‎, ‎based on theory of dynamical system‎. ‎A low dimensional Lorenz‎- ‎like model is obtained by using Galerkin-truncation approximation‎. ‎We found that there is proportional relation between scaled couple stress parameter and rescaled Rayleigh number‎. We analyzed that increase in level of couple stress parameter increases the level of chaos‎.
