RÉSUMÉ

The Darcy-Lapwood-Brinkman model with the Boussinesq approximation is used to study the linear and nonlinear stability analysis and obtain the conditions for the occurrence of various types of bifurcations, viz., Pitchfork bifurcation, Hopf bifurcation, and Takens-Bogdanov bifurcation points. We have used stress-free boundary conditions and derived a nonlinear two-dimensional Landau-Ginzburg equation with real coefficients at the supercritical pitchfork bifurcation and discussed the effect of Nusselt number on the heat transport by convection. We have shown the occurrence of secondary instabilities such as Eckhaus and Zigzag instabilities. We also derive two coupled one-dimensional Landau-Ginzburg type equations with complex coefficients near the onset of oscillatory convection at supercritical Hopf bifurcation and discussed traveling and standing wave convection.
