The instability of through flow in a horizontal porous channel with uniformly heated boundary walls is investigated. The analysis is based on the solution of the linearised perturbation equations expressing the local mass and energy balances, as well as the momentum balance modelled according to Darcy-Forchheimer's law. The neutral stability data are obtained in terms of the dimensionless governing parameters, namely the Darcy-Rayleigh number, the Peclet number, and the form-drag parameter.

Abstract
The instability of through flow in a horizontal porous channel with uniformly heated boundary walls is investigated. The analysis is based on the solution of the linearised perturbation equations expressing the local mass and energy balances, as well as the momentum balance modelled according to Darcy-Forchheimer's law. The neutral stability data are obtained in terms of the dimensionless governing parameters, namely the Darcy-Rayleigh number, the Peclet number, and the form-drag parameter.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
