Particle injection in DPM

March 15, 2007, 04:41

Hi

I am trying to inject fuel using DPM model. In injection pannel there is a option 'no. of particle'. I have to ask what is the effect of increasing or decreasing the number of particle on solution. I am using plane orifice atomizer.

Thanks in advance

No of particles u are specifying in the panel is the number of particles you are injecting at a time. if you specify 1 there will be only one particle stream in the domain. So if you increase it u will get more distributed particle streams in the domain
