Abstract
AbstractThe aim of this survey is to give a concise but technical and, as much as possible, comprehensive introduction to the resolution of certain eigenvalue problems occurring in the research field of hydrodynamics via theChebyshev-$$\tau$$τmethod. While many details on the construction of mathematical models (for which we will refer to notable and well-known references as reported by Chandrasekhar (Hydrodynamic and hydromagnetic stability, Dover, London, 1981); Straughan (The energy method, stability, and nonlinear convection, Springer, New York, 2004); Nield and Bejan (Convection in porous media, Springer, New York, 2017)) will not be given, much attention will be paid to the practical and theoretical aspects of the discretization of the continuum problem.Chebyshevpolynomials will be employed to expand solutions of the differential eigenvalue problem and end up with a discrete eigenvalue problem. Finally,MATLABcodes for the considered problems are shown in detail and available onGitHub.
