Lorenz and Ginzburg-Landau equations for thermal convection in a high-porosity medium with heat source

The paper presents an investigation of a weakly non-linear stability analysis of thermal convection in a porous medium using the Lorenz model. The Ginzburg-Landau model is then obtained from the Lorenz model using which an expression for Nusselt number, Nu, is obtained in closed form. Such a procedu...
