On the stability of the conduction regime of natural convection in a vertical slot

The stability of the conduction regime of natural convection in a vertical slot has been studied analytically. For Pr Pr > 12.7 the instability sets in as a travelling wave. As the Prandtl number is increased the onset of instability approaches the correct limiting solution which is constant as a function of GrPr1/2.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/33827/1/0000084.pd
