Impose a diffuse flux in an inlet
Hi!
I'm studying a simple case: an enclosure with an inlet and an outlet. The boundary type for the inlet is 'pressure_inlet' and it lets me enter a flow direction. Nonetheless I don't want all the flow entering the enclosure to have the same direction, I want a diffuse flux where most part of it (let's say 70%) is in the direction perpendicular to the inlet surface whereas the rest of it has a random direction (something similar to the lobe that defines the intensity emitted by an antenna... do you know what I mean?) How could I impose this flux in FLUENT? THanks! |
Hi,
You can define a udf for defining profiles for the velocity as boundary condition for an inlet. There is a nice example in the udf documentation. |
Thanks!
But now I have another problem: I wanted to impose 3 profiles. One for each velocity direction. The problem is that, even if I interpret three source files in FLUENT (Interpreted UDFs panel) when I try to hook them to each velocity component in FLUENT it only recognises the last one I interpreted... so at the end I can only specify one of three profiles. What I'm doing wrong? FLUENT cannot use more than a UDF Boundary condition? |
