Prediction Model for Pressure Drop of Single-Phase Flows in Porous Media Channel

Compared with that in the conventional pipes,the fluid flow in porous media channels is more complicated and the flow resistance increases dramatically,which makes it difficult to predict the pressure drop exactly.The pressure drop can be predicted by developing the porous media channel model and solving N-S equation.But it can not be used widely,because of a great quantity meshes.In this paper,based on the similarity theory,a prediction model for pressure drop in porous media channels was developed using Flu-ent6.3.The adiabatic flow was numerically simulated by solving the three dimensional N-S equation.The comparison with the experiment results showed that the predictions agreed well with the measurement of various working conditions with an error less than 5 %.
