Pressure difference after adding injectors in Prostar

aziz56 · December 15, 2011, 08:35

Hi
I need ur help
i have simulated a moving chamber with it valves , using prostar
after i simulate i have good pressure values (maximum pressure at tdc =45bar) after changing it to lagrangian multiphase and adding the injectors i have a pressure difference of 13bar at the same point do any one knows why ??

(fuel ration have been added in prostar option spraywithatomazation all the other options have been add in prostar )
do you have idea why there is a big difference betwwen the two simulations

thxs alot

How to move piston and valves in prostar, it shows cell deactivation error every time i try to deactivate cell using events file. Is there any procedure before deactivating a cell like moving grid commands or detaching the cell from the simulation. It would be very helpful if you point my errors.

Thank you.....

@Subash why are you trying this in prostar? Do you have access to es-ice?

I have access to es-ice but I wanna know how to create a geometry and mesh it in prostar and also give event files to moving piston inside a cylinder.
