- •
Form drag effect on double diffusive and Soret convection within tall porous layers.
- •
Form drag shifts drastically the onset of subcritical convection.
- •
The form drag has a stabilising effect and delay the onset of subcritical convection and Hopf bifurcation.
- •
The drag from leads to bistability phenomena below and above the threshold of supercritical convection.
- •
Form drag induce traveling waves within the overstable regime.
