Modelling bidispersive local thermal non-equilibrium flow.

Franchi, Franca and Nibbi, Roberta and Straughan, Brian (2017) 'Modelling bidispersive local thermal non-equilibrium flow.', Fluids., 2 (3). p. 48.

Abstract

In this work, we present a system of equations which describes non-isothermal flow in a bidispersive porous medium under conditions of local thermal non-equilibrium. The porous medium consists of macro pores, and in the solid skeleton are cracks or fissures which give rise to micro pores. The temperatures in the solid skeleton and in the fluids in the macro and micro pores are all allowed to be independent. After presenting the general model, we derive a result of universal stability, which guarantees exponential decay of the solution for all initial data. We further present a concrete example by specializing the model to the problem of thermal convection in a layer heated from below
