Abstract

The main objective of this paper is the determination in the parameter space of the neutral hypersurface which separates the domain of stability from the instability domain in a problem of stationary convection in a micropolar fluid [1]. The influence of each of the micropolar parameters on the eigenparameter represented by the Rayleigh number is investigated using a spectral-Galerkin method based on expansion functions proved to assure an exponential convergence and small computational time expenses.
