Abstract :
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.
