Many interesting questions

1) Dealing with gaseous fuel (C7H16), what data should I supply in the molecular properties: the one for the liquid (from the STAR database)or the one for the gaseous state? For example, can I set molecular properties for the liquid at the Additional Scalars' Molecular Properties and define the boundary conditions as for the gas?

2) How do co-exist the scalars concentrations that I give at the Scalars Boundary and at the Define Boundary Conditions? Should they be the same?

3) What concentration values should be set at the pressure boundary?

4) I obtain a recirculation zone where it shouldn't be obtained (I think that the reason is in using the pressure boundary). How can I avoid this?

Hello Julie,

1.When the scalar comes from the evaporated liquid fuel you have to specify properties for the gaseous state. 2.Is there a difference?

regards Franz
