Hi, I want to inject fuel in a gaseous phase using diselFoam.
The gas-phase is no problem since I just increase the temperature. The thing is that is want to have two injections using 0.7mg of fuel at each injection with a 200microseconds injection duration. I thought that is simply could write something like mass 1.4e-6; nParcels 2; massFlowRate (0 0) (0.0002 0.0016) (0.003 0) (0.0032 0.0016) the 0.0016 was calculated using Cd*Af*sqrt(deltaP*2*rho(fuel)) Any good reason why this do not work? I have looked at the other threads still my problems remains. Thx R |

I guess i fixed my own problem.
Important notice is that the pressureProfile must be added I try to use injection as a delta function or whatever you wanna call it. so . mas... (0.00019 0) (0.00020 1.0) (0.00021 0) (0.00319 0) (0.00320 1.0) (0.00321 0) press.. (0.00019 1.0) (0.00321 1.0) Hopefull dieselfoam calculates the massflowrate on its own- |
