inertial and viscous resistance coefficients in metal foam

Wi A Sa · December 1, 2017, 06:48

hi everyone
Im new in metal foam ( open-cell-aluminum-foam )
porosity equal 0.93 and PPI equal 10 and I have pipe with metal foam.
How can I calculate inertial and viscous resistance coefficients in metal foam to set it in ansys-fluent ?
and i work on 3-D .. i set the values in three direction in same value or Y and Z direction have a greater value ?

I am also searching to find the inertial and viscous coefficient for nickel material with porosity of 0.9.
If you get any help kindly let me know.

Hi,
Have you already know how to calculate the viscous and inertial resistance for foam? I'm currently doing the similar simulation to yours.

Regards
Alan
