Numerical Study on Resistance Characteristics of Single-Phase Flow through Porous Media

This paper studied the resistance characteristics of single-phase flow through porous media in numerical way. The flow field is modeled by the Brinkman-Darcy-Forchheimer model. The results obtained from this model agree well with the experiment results. The resistance loss coefficient K_loss of the model has been discussed. It is founded that K_loss dominated the resistance and the influence of Reynolds number on K_loss should be taken into account when Reynolds number at the high values.Numerical results also show that the resistance decreased with the increasing of dimensionless diameter D.
