HI all..

I wish to model porosity for one large tunnel model. Hove tried one times but the temperature raise extremely. Any recommendation for this probs others than alpha beta or porosity values.

Thanks in advance.

Hi

- What values are you using for alpha, beta and porosity ?

- What is the purpose of simulation ? Do you want to simulate pressure drop only or flow acceleration also ?

Thank for respons,

My setting is alp: 42.5e+5 , bet: 13.5e+7 and 0.5 porosity values. The Comp.Domain is very large (8150*22000)mm Actually i want to simulate pressure and temperature drop through one large channel with different cross section area between inlet and outlet. Hope some advise.Thanks a lot.
