Transitions and bifurcations in couple stress fluid saturated porous media using a thermal non-equilibrium model

作者:

Highlights:

• Dynamic transition theory is used on couple-stress fluid saturated porous media convection problem.

• Complete description of the global dynamics on and during the onset of convection is obtained.

• Approximate bifurcated solutions are given and corresponding roll structures are visualized.

• Transition types are determined during the onset of convection.
