Stability problems in fluids at rest — Bénard instability
Let us consider a horizontal layer of fluid in which a temperature gradient is maintained by heating from below (the so called “adverse” temperature gradient). For sufficiently small values of this slope,heat is transmitted only by conduction. However beyond a critical value convection appears.
