I am modeling what is essentially a piping Tee (24"x30"x30") with 46 small holes drilled in the 36" side. The fluid is water. The inlet is the 24" side. This Tee is meant to diffuse water instead of dumping it into a tank directly from the pipe. The project is titled Tee Diffuser - Incompressible CFD.
The first run I performed produced results with unrealistically high velocities. I used a k-omega SST model. I defined the inlet as a volumetric flow rate with the outlets being pressure (0 psig). I also tried defining a uniform velocity inlet, but this produced similarly high velocity results.
I closed off all of the small outlet holes, so only the two 30" legs of the Tee were outlets. This produced results that make sense. It seems the 46 small holes are causing problems with the solver.
I am new to using SimScale, and CFD software in general, and am not sure how to proceed with getting results accounting for flow out of the small holes. Any help is appreciated.
