Pumps, Compressors, Valves
Purpose: With the advent of high quality resin 3D printing, I always thought it would be kind of neat to create a mold and sand cast a part. Fun fact but a lot of components in turbochargers are sand casted; most notably the compressor cover, turbine, and bearing housings. I model the parts below and obtain a CFD solution (no design parameters):
Volute:
Compressor wheel:
Assembly [Compressor stage]:
Using water as a working fluid. Noticed something was off with the pressure outlet within ~5 minutes. Let it finish running.
Chose the wrong direction for my rotating region. I changed the direction and reran it. Totally planned this.
Looks way better. Pressure outlet is starting to make more sense.
Nice to see the cut plot show where the velocity is at a maximum, the pressure is at a minimum. This is verifiable by Bernoulli’s equation whereby pressure is inversely related to velocity.
