jeff_F New Member ManChiu Join Date: Jul 2009 Posts: 13 Rep Power: 16	Hi all. From the FLUENT user guide, I found that the droplet size formed by pressure swirl atomizer model is calculated by Rosin-Rammler distribution with spread parameter of 3.5. I would like to change this value into other numbers. Can it be done by UDF? I've checked the UDF user guide and the dpm.h file already, but I can't find a relevant variable. Hope I can hear from you guys soon. Thanks in advance
