reference pressure

iperten · March 31, 2009, 03:48

Dear all,

good morning.

I have a very fast question: in CFX, for a compressible flow, a reference pressure is defined, such that abs_press = stat_press + ref_press.

Is that true for the total pressure as well?! I mean: is the total pressure given in CFX-post, for example, also relative to the reference pressure? If yes, I suppose that my "real/final" total pressure is the sum of the reference pressure and the total pressure taken from CFX-post.

Thank you, kind regards, Mattia.
