I set the intake boundarieas as pressure. And I supply EGR gas through one of the two intake ports. The pressure and temperature of the two ports are the same. But I finded that when calculation is going on, the inflow velocity of the two ports are so different. Velocity of the port with EGR is much lower than the other port. It is unreasonable. I want to know the reson.Anybody can help me?
