Is their difference in velocity distribution in porous media and empty pipe. I am doing simulation using physical velocity in porous media. But i can't see the difference in velocity in porous media and without porous media section

What resistance coefficients did you set? Please plot contours of velocity to illustrate the problem. 

[Amine Ben Hadj Ali]

Using superficial velocity formulation you will only see pressure drop.

I am using physical velocity formulation in cell zone condition but there is no velocity change. i can see only pressure drop. i am using standard initialization. If I am wrong please correct me.

viscous  resistance 4.09e+10 and inertia resistance 107306.7

Can you plot path-lines colored by velocity magnitude through the porous zone. 

[koltesomesh20]

I had plot streamlines for velocity but their is no difference in colour and magnitude

[Rob]

Please post the images, pressure drop and velocity. Also please add any solutions on here rather than keeping them to yourself! 

[koltesomesh20]

hi..I got the solution. Use physical velocity in fluid dialogue box. And also use only standard initialization if u use habride initialization u will not reach to actual solution

[koltesomesh20]

When porous material in thermal equilibrium with fluid. Can we get temperature drop in fluid along the pressure drop????

[Rob]

Have a look in the contours. 

[koltesomesh20]

is their someone working in refrigerant flow through porous media????

I need some help please....

[Rob]

Maybe add some images? Amine and I have suggested a few plots, sharing those would help us understand what you're doing.
