Abstract

A collocation technique is applied to the equations governing the linear stability of the anabatic layer on an evenly heated vertical wall in a stratified fluid. Marginal stability curves and critical heat fluxes are obtained for Prandtl numbers from 0 to 1000. As in other cases of vertical natural convection, two kinds of instability are observed, depending on the Prandtl num- ber: at lower Prandtl numbers, the modes are short slow waves and the critical parameter is roughly proportional to the local Reynolds number, whereas at higher Prandtl numbers, the criti- cal Reynolds number decreases rapidly and the waves are longer and faster.
