Body Force for Droplets

ck5285 · June 23, 2009, 01:09

Hi All
For droplets modeling for example inkjet droplets modeling, is the inertia due to fluid body force been considered by F3D solver? if Yes then how to turn it on? Thanks.

what do you mean by "the inertia due to fluid body force"?

when fluid been pushed out by piston/pressure, fluid will experience two velocity components one is velocity induced by piston/pressure and second is acceleration due to the weight of the fluid itself (body force). So, is this been considered in F3D?

by body force, did you mean gravity or something? if it is gravity or something equivalent, you may just specify it with the gravity setup.

Thanks for the feedback.
