Using Transient Boundary condition

I plan to use FLUENT to simulate fluid flow and heat transfer in tubes/channels. But the inlet boundary condition is going to TRANSIENT , i.e., inlet flow rate varies with time. Flow rate can change from a very small value (hence laminar) to a very high value (hence turbulent) and a very high value to a very low value OVER A PERIOD OF TIME. Can FLUENT switch over from LAMINAR to TURBULENT and TURBUELENT TO LAMINAR automatically over a time period based on the transient boundary condition (inlet flow rate or velocity changing with time)?
If yes, can anyone please explain how it can be done. |
