the user guidline says that the vapor pressure in plain orifice atomizer injection is the vapor pressure governing the flow through the internal orifice in the Vapor Pressure field. It's not the upstream pressure nor the downstream pressure. but I can only be sure about that the upstream pressure is 0.2Mpa， the downstream pressure is 0.1MPa. So how to set the vapor pressure in the plain orifice atomizer injections? according to what? thanks a lot.

Obviously this is 2 years late but for anyone else who comes across this I think the vapour pressure you need to supply is the fuels vapour pressure.

Can find values for most common fuels here:
