This paper presents the results of a numerical investigation in transient regime on a single slot jet impinging in a porous parallel-plate channel containing an air-saturated high permeability porous medium. The bottom wall is partially heated, the effect of buoyancy is also taken into account. The fluid flow is assumed two dimensional, laminar and the porous medium is modelled using the Brinkman–Forchheimer-extended Darcy model in local thermal non-equilibrium hypothesis. Results in terms of non-dimensional average wall temperature profiles and average Nusselt numbers are given.

Abstract

This paper presents the results of a numerical investigation in transient regime on a single slot jet impinging in a porous parallel-plate channel containing an air-saturated high permeability porous medium. The bottom wall is partially heated, the effect of buoyancy is also taken into account. The fluid flow is assumed two dimensional, laminar and the porous medium is modelled using the Brinkman–Forchheimer-extended Darcy model in local thermal non-equilibrium hypothesis. Results in terms of non-dimensional average wall temperature profiles and average Nusselt numbers are given.
