Does anyone know accretion rate?

May 10, 2005, 17:31

The help of FLUENT does not say much about it. I wonder if it can determine how many droplets deposit on a sphere target of a spray problem.

But I found that even if I don't specify the boundary condition of the sphere as "trap", it can report surface integral of accretion rate.

What the hell is "accretion rate"???

Thanks

I have tried to use DPM and accretion rate, but I got wierd results!~ I don't know if this option is just dealing with solid particle, not liquid? (My particles are liquid from a spray nozzle) Thanks a lot!

it deals with particles either liquid and solid.
