HRSG Simulation
 

I have made the geometry and have meshed it in Gambit (in 2D ).

I applied the boundary zones in the following way.

1. Water Pipes -- Wall BC.

2. One Edge as --Mass Flow Inlet

3. another edge as --Pressure Outlet

When i export it to Fluent, it loads properly but when i go to specify the boundary conditions at these zones. The 'mass flow inlet' and 'pressure outlet' zones are not listed there.

May i add i am new to CFD. So, your help will be greatly appreciated. Its my final year project.

Thanks in advance.

OpenFOAM isn't supposed to recognize the kind of BC you set up, but it will recognize the patch name you gave in Gambit.

I see but for some reason it was not even recognizing all the patch names.

However, i am now using ANSYS 12.0 to solve the case and i am facing another difficulty. I am new to CFD analysis and i cant seem to figure out how to use wall BC to simulate heat transfer between two fluids.

I am analyzing the heat transfer between two fluids separated by a metal pipe. I am using the wall boundary condition to separate the fluids. However, i am unable to understand how to use the wall BC.

Can anyone help me with this? any examples or tutorials than can be of help? Thanks in advance! :)
