Numerical simulation on forced convection heat transfer in porous media using Gibson-Ashby constitutive model
In this article, using Gibson-Ashby constitutive model, we suggest a new method for numerical investigation of forced convection heat transfer in porous foam metal, and try to consolidate the study for mechanical property and that for thermal characteristic. By available experimental data, we simulated to two cases, namely as the transfer in porous media for diameter is 0.6mm and porosity is 0.402, and for diameter is 1.6mm and porosity is 0.462. The result, from our constitutive model for single forced convection heat transfer, corresponds well with the experimental data As for pressure drop prediction in porous is in good agreement with experiment, and the error is only 5％ to 10％, but for transfer is less accurate, the error is about 20％, which is acceptable in practice. So it is done that constitutive model is used to simulate the transfer property.
