Abstract
The linear stability of fully developed, mixed convection in an annulus of large aspect ratio is studied. At an aspect ratio of 100, the effect of wall curvature is minimal, and both the base flow and its stability characteristics approach those of a two-dimensional channel flow. The linear-stability results demonstrate that the fully-developed flow is unstable in regions of practical interest in an appropriate parameter space. Consequently, commonly assumed parallel countercurrent flows in many idealized numerical and analytical studies can hardly be observed experimentally.
