A general two-equation macroscopic turbulence model for incompressible flow in porous media
B.V. Antohe,José L. Lage +1 more
TL;DR: In this article, a two-equation turbulence model for incompressible flow within a fluid saturated and rigid porous medium is presented, which consists of time-averaging the general (macroscopic) transport equations and closing the model with the classical eddy diffusivity concept and the Kolmogorov-Prandtl relation.

Review on numerical modeling of active magnetic regenerators for room temperature applications
Kaspar Kirstein Nielsen,Jaka Tušek,Kurt Engelbrecht,Sandro Schopfer,Andrej Kitanovski,Christian R.H. Bahl,Anders Smith,Nini Pryds,Alojz Poredoš +8 more
TL;DR: In this paper, the authors reviewed the existing numerical modeling of room temperature active magnetic regenerator (AMR) to date and concluded that more detailed modeling of these phenomena is required to obtain a better understanding of the AMR cycle.

Numerical model and experimental validation of heat storage with phase change materials
Jacques Bony,Stéphane Citherlet +1 more
TL;DR: In this paper, a numeric model based on the enthalpy approach was developed to simulate heat transfer in phase change materials (PCM) in water tank storage, taking into account the conduction and the convection into PCM as well as at the interface between PCM and water of the storage.

A General Method of Obtaining Approximate Solutions to Laminar and Turbulent Free Convection Problems
G. D. Raithby,K.G.T. Hollands +1 more
TL;DR: In this paper, the authors focus on determining equations for the local and mean rate of laminar heat transfer, which are approximately valid for different geometries by use of these equations, several new correlations are obtained for various heat transfer problems, and the results compared with experiments.
