Hi everyone,


I have some trouble with discrete phase model in fluent 15, namely no evaporated. All tracked ecaped I attached screen shot on it.


mash 3500000 volumes

Boundary conditions
mass flow inlet 0.3 kg/s 400K
pressure outlet 200000 Pa
total mass fuel 0.066 kg/s (jet-a)

6 injection - Only differing localization

DPM options
tracking parameters - max. number of steps 100000, length scale 0.001m
number of continouis phase interations per DPM iteration - 1
Spatial Discretization, first for all parametres
under-relaxation factors 0.1 for all parameters


First 3000 iterations is compute only cold flow and next turbulence, energy and PDF


I would be grateful for any help


I noticed a mistake in the first screenshot. Flow Rate it should be 0.00011 (0.0011 at present) , number of streams are correct - 10
0.00011x10 x 6(injection) gives the result the assumed 0.0066kg/s - correct me if I'm wrong
