Hello everyone,

I would like to know, should I use multicomponent droplets for a solution mixture like urea water solution, or I just use single component? anyone with the same experiences?

Thanks

When water evaporates, urea-water creates melted particules. This is not good for the exhaust.

I would advise you to consider the option of performing an hydrolysis of the urea-water before injecting it:

Then you can simulate the exhaust after the hydrolysis once the water-urea is in gas state.

Thank you for the idea, yes it is a good option. One more problem is the Urea water solution, urea(gas), and isocyanic acid properties that is not exist in the STAR CD database, anyone know where to find it?

THanks
