How to create an inlet with pressure gradient?
Hello!
I would like to create an inlet pressure gradient (with FLUENT) in order to study the behaviour of a pressure probe. This is a work i'm doing for my diploma thesis. Unfortunatly, I don't know how to create this pressure gradient. Could somebody help me please? Regards Valentin |
Just a precision:
When I say "pressure gradient", I mean I want my pression to be greater on a side of the inlet (a square shape inlet) than on the opposite side (with a linear relation for example). Sorry if what I wrote is not clear, but I'm french and it's a long time I I haven't learn English.... |
Please, I really need to know how to do that, I have alomost finish my dilploma thesis, but I miss this!!

got a similar problem with a temperature profile on a tube.
i think you have to use User defined functions. here my example: #include "udf.h" DEFINE_PROFILE(temperature_profile,t,i) { real x[ND_ND]; real z; face_t f; begin_f_loop(f,t) { F_CENTROID(x,f,t); z = x[2]; F_PROFILE(f,t,i) = 343.15 - 20.0*z/1.0; } end_f_loop(f,t) } here i wanna a temp at the begin of 343.15K(z=0m) and at the end 323.15K(z=1m) to watch some more examples download the manual for UDF (Fluent) good luck |
Great!!
Thank you very much, I found it in the UDF manual. However, I need to give an incidence angle to my pressure gradient (in the two direction x and z, it's a 3d problem), but I haven't find anything about this. An Idea? Regards |
i recommend to write the function as you think it could be, and write a new thread.
i did the same, people answer you mostly if your question is concrete. good luck |
