Stability of convective flows in porous media

Creator:

Ghandour, Nabil Nassib

Abstract:

The stability of fluids in porous media subject to various physical and geometrical conditions is studied here. Criteria for the onset of convective motions are given in terms of critical temperature gradients or heat sources. The general method used involves the linearization of the field equations about the hydrostatic solutions...

Stability of flows of thermo-viscoelastic fluids between rotating coaxial circular cylinders

Creator:

Ghandour, Nabil Nassib

Abstract:

We investigate in this thesis, the problem of stability of thermo-viscoelastic fluid flow between rotating coaxial cylinders. By using the thermo-viscoelastic constitutive equations given by Eringen, we reduce the equations of motion into a form suitable for stability analysis. The course of reduction which we follow yields some interesting intermediate...
