Stability, viscous dissipation and local thermal non-equilibrium in fluid saturated porous media

摘要: In this thesis, the field of study related to stability analysis fluid saturated porous media is investigated. particular contribution viscous heating onset convective instability in flow through ducts analysed. order evaluate dissipation, different geometries, models describing balance equations and boundary conditions are used. Moreover, local thermal non-equilibrium model used evolution temperature differences between solid matrix a layer problem. On studying instability, techniques for eigenvalue problems has been Analytical solutions, asymptotic analyses numerical solutions by means original commercial codes carried out.
