I have been tryin to do a flow sim on my FSAE project and i'm trying to find my way out through a tricky stuff. I want to simulate my intake(flow sim) for 2 situations.
1) Well I have been able to perform this type of simulation. The boundary conditions for the inlet is pressure(1 atm) and at the runners it varies.
2) This is where i face real trouble. As the car moves along, there would be a velocity of air gushing in through my forward facing intake. But the trouble is i cannot compare the of effect with and without velocity.
Sadly flowsim doesnot allow the defination of more than one type of inlet boundary condition. I would like to know a method in which i can define the inlet boundary condition as both 1 atm and x m/s velocity.
Much appreciate your help,
