Hi everyone, was hoping someone could help guide me in the right direction with this problem.<\/p>\n

I am designing a ramjet geometry using matlab but I want to model it in Fluent as well. Preferably tip to tail but if I need to break up the sections its fine. However, we are supposed to model the Flameholder section as a pressure loss according to this formula: <\/p>\n

\"\"<\/p>\n

 <\/p>\n

This pressure loss region would be at the line marked “3” in the picture below.<\/p>\n

\"\"<\/p>\n

Modeling this is matlab is straightforward but in Fluent is another matter. I am confident in how to model all the other sections but am at a bit of a loss on how to model this pressure loss. This would be a 2D simulation so the pressure loss would be a straight line across the combustor region. I’ve seen a few things regarding using the porous media model\/tool thing as a potential solution but I am not confident in that approach. <\/p>\n

Any help\/advice\/guidance would be appreciated.
