bugra is on a distinguished road
hi everybody,

i want to see the water (goes out from a nozzle) spreading in air, how long it arrived at defined height, the problem concludes g force, 3D.

i use vof model, i want to see in interview of 1bar and 7 bars inlet condition to nozzle, and unsteady solution,

but after about 0.1 second, the problem begins to diverge. while selecting multiphase model in fluent, in VoF, explicit is selected as default, courant number is 0.25 selected and open channel flow is unselected.

i used both simple and piso algorithm too,
is there any body studied this before, or anybody can explain anything?

thanks...
