Diameter of particle dpm
Hi everybody,
i have problem with transient injection in a dpm simulation. i should want an injection of particle with the diameter of nozzle-hole, then with "point injection" the particle diameter should be the same of diameter point, that i set 0.00014 m. I can't undertand why there are particle with diameter that is 0.00025m! Can you help me? thank you!! |

Where did you set the diameter and how did you get the particle diameter in fluent? |
Dr fishball,
I apologize for the late reply but i was abroad. In the discrete phase model i create an injection and i choose respectly: injection type -> solid cone diameter distribution -> uniform point properties -> diameter = 1.4e-04. Can you help me with these large bubbles that i find in the spray with a diameter bigger than the fixed size? thank you! |

Hi fishball,
during the injection at some time the nozzle injects these large bubbles. I find them in a random position respect to spray axes at the end of the injection time. They are about 15-20! |

is collision and coalescence turned off?
