Fluent newbie in need of help w/unsteady flow
For the last 2 weeks I have tried to model an unsteady flow with no viable results.
Create a 10 meter in diameter cylindrical tank with an outlet nozzle of 1 meter in diameter. How long does it take the fluid level to drop from 30meter above the tank outlet to 1 meter above the tank outlet?
The top of the tank is open to the atmosphere.
I have done the following:
- Created geometry in GAMBIT. (30m height, 10m diameter, w/nozzle 1m above bottom)
- Once in FLUENT:
-Pressure set at 101325 Pa
- Gravity check marked
- Open top of cylinder: Vent Inlet @ 0 psig
- Nozzle exit: 1 flow rate
-All checked marked (1x10^-5)
-Time and delta time: print
- No initial conditions since at time zero draining has not begun.
- NOT SURE WHAT TO DO HERE!:eek:
PLEASE HELP!!! I am worn out from trying everything possible! (except the right approach:confused:)
