Boundary conditions for fluid flow

Project Support
1

Hello team,

I am trying to do flow analysis of air.
I want to determine what will be the velocity of air after it passes through a venturi. I want to calculate output for input velocity- 1m/s, 2m/s,…, 5m/s. and this is the only input I have. I don’t know conditions at outlet.
What boundary conditions should I apply?

Hi there, to begin with, you will have to create an internal flow volume and then remove all solid bodies in CAD mode. Then it is recommended to use a velocity inlet and a pressure outlet boundary condition, have a look here: Define the boundary condition - #4 by tsite
