soil surrounding
Hello everybody I forgot to state that the pipe I should model transient natural gas flow in, is buried under the ground and I should also model heat transfer . So there exists three layers, i.e a gas layer bounded by the pipe and the soil surronding the pipe. Can I model heat transfer in this problem while modeling mass transfer? Please help me. Thanks

Re: soil surrounding
hi Leila,

Fluent can model conduction in solids. you should have three seperated zones in your model, a fluid zone for gas and two solid zones for pipe and soil, respectively. Do not forget to give properties of gas, pipe and soil in the material panel.

good luck.
