Abstract

This paper proposes an analytical solution to the stationary linear Rayleigh problem for a convective cell in a cylindrical geometry with solid boundary conditions. On its basis, analytical expressions for neutral curves in the case of solid and mixed boundary conditions are constructed. It is shown that the neutral curves correspond to the numerical calculations obtained by other authors with a sufficient degree of accuracy.

 

Keywords: Rayleigh stationary linear problem, cylindrical geometry, solid or mixed boundary conditions, analytical solution, neutral curves
