free exit boundary (outflow boundary)

Recommended Posts

Hello Wise Ones,

I am trying to use EOS7C is model a methane plume that originates via subsurface injection and is allowed to leave the model through the top boundary. How can I implement a free exit or outflow boundary for methane (or any NCG)?

Thank you!

Amy

Hi Amy,

I think that most people would simply use a fixed state boundary cell to represent an open boundary. When a cell is specified as "fixed state", fluid (and gas) can flow in and out of the cell without effecting the pressure, temperature and phase state of the cell.

Best Regards,

Alison
