Hello
I am modeling a two phase problem. one phase is the air and other is grain bed. I need to calculate pressure and velocity distribution of air through the bed. Height of bed is 1 meter. although the grains is discharging with known mass flow rate from the bottom of bin. therefore air and grain are moving counter flow. my questions are:
1- Can I use two phase Eulerian model?
2- What type of B.C must be selected in out let of grain?
3-Is this problem assotiated with the porous media?
Thanks
