Two of them are samller than the others. I try two kinds of set to show the unequal mass flow. spray1 is a injector with 5 different-diameter nozzles. Spray2 has two injectors, one has two nozzles and another has there nozzles. Other settings are the same. I think the results would be no difference, but I got very different results especially the wall film. Now I am confused which is right.
