Abstract : The differential equations for small perturbations of the basic viscous and heat flows in the problem indicated are derived, and the critical conditions are obtained for a number of cases, each treated in a separate section. The results obtained elucidate the physical equivalence of the viscous and thermal causes of instability and establish the effect of their interaction on instability in terms of an interaction parameter. It is thus found that transitions, which can be individually produced by separately applying velocity or temperature gradients, are strongly conditioned by the interaction of these gradients when applied simultaneously.
