Abstract
The influence of an axial convective motion caused by radially nonunif orm heat sources on the stability of a Couette flow between cylinders, if the inner one is relating with constant angular velocity and the o uter one is fixed, is studied in this paper. The axisymmetric and the first few asymmetric modes are studied. It is found that, for wide gap s, there exist regions of stabilization of Couette flow. These regions , which correspond to asymmetric modes, decrease as the Prandtl number grows.
