DMP mass flow rate

I am working on a sampler case using the discrete phase model in FLUENT. I was wondering what the mass flow rate you set in the injections window does. It seems to me that if you specify a particle diameter, particle density, and an initial velocity that the mass flow rate would be set by these parameters. The problem seems to be over specified. I know this is not the case and I am hoping someone could correct my confussion. Thank you all in advance.

In reality, there could be say a million particles per second entering a domain, but you only have computational resouces to model a thousand. So each of the thousand is representative of many more particles. There is a factor that lets Fluent know how much of the overall particulate phase is represented by each particle.

Thanks for the quick response. That helps a lot. The FLUENT manual does not make much mention of this fact.

what is the factor u r talking about? In what way fluent will do correction for those things? As i have understood it calculates for the value of parameters we have given.
