Hi everyone
I'd like to perform a simulation of a jet of burning kerosene in an duct. Could someone help me about the meaning of the parameters in the injectorProperties dictionary (in particular the Cd and nParcels parameters)? I want to specify a constant mass flow rate of liquid from the injector and I would like to have some control on the liquid particle dimension injected. unitInjectorProps { position (0 0.0995 0); direction (0 -1 0); diameter 0.00019; Cd 0.9; mass 6e-06; temperature 320; nParcels 5000; ...... Thank you Antonio |

I have another doubt
I suppose that the models for drag, evaporation ecc are related to particles dimension. I haven't understand the relation between parcel and particle for what concern dimensions. When a parcel is injected (according to the specified massflowrate and nparcel) what are its characteristics? What is the diameters of the particles that are represented by the parcel? |
