which process should i track? i want to do modelling in STARCCM+ have you ever modelled before like this example? Can you give me some information, we want to decrease NOx emmisions in biyodisel fuels

I haven't use CCM+ before (I use Star) but I think that's a gret challenge...because...you need to define a fuel "ad hoc" is it? And his properties influence atomization, breakup, evaporation...everything! I think that if you have all the required information for a real biodiesel fuel you can try to so something, if you don't I don't think you'll succed... You need to define fuel, his properties, turbulent reaction...what we "teorically" can do for the normal diesel fuel but that in fact we can't!
