The onset of nonpenetrative convection in a suddenly cooled layer of fluid
Conditions for the onset of nonpenetrative convection in a horizontal Boussinesq fluid layer
subject to a step change in temperature are studied using propagation theory. A wide range
of Prandtl numbers and two different kinematic boundary conditions are considered. It is
shown that for high Rayleigh numbers, critical conditions for the onset of convective motion
reproduce exactly those for the unsteady Rayleigh–Bénard instability. Present results extend
those of previous research and show a tendency of the rigid–rigid and free–rigid critical …
