• Non-linear solutions and their stability are presented in this work for homogeneously heated flows with a simple geometry under the influence of a constant pressure gradient or when the constant flux constraint across any lateral cross-section of the channel is imposed. The critical Grashof number is determined by a linear stability analysis for various values of the Prandtl number. In our numerical study the angle of inclination of the channel is taken into account and we found that in each case studied, with the exception of a horizontal layer of fluid and when the applied constant pressure gradient is zero, the basic flow looses stability in a Hopf bifurcation. Following the linear stability analysis our numerical studies are focused on the emerging secondary flows and their stability, in order to identify possible bifurcation points for the tertiary flow.
