Spray modelling
 

hello

i tried to model a diesel spray injection in a cube fluid domain with 2 Mpa ambient conditions

the model settings are
1. plane orifice model
2. wave -break up model

while other data was pretty much standard

now if you see the particle diameter distribution ,the particles are supposed to break up at the front of spray.. but instead i am having large diameter particles at front of spray as compared to those at injection point

can someone explain is this correct or the reason for such a anomaly

thanks :)
