Hi every one. I`d like to simulate the displacement of a fluid like oil when is pushed by water through a pipe.
I don`t know if that is posible and how do it.
Might get a reasonable approximation with flow but likely tricky.
Then, It's posible? I'm new with this software.I`ve drawn an small pipe with two lids (IN and OUT) and water with a flow (30m3/h) but I want to put inside oil (or another fluid with hight viscosity) to know the displacement of the two fluids and how much is the interfase.
Can you help me? Thanks
what are you trying to learn in this simulation?
i don't think you can do this in flow, there is no real way to define the fluid subdomain. you'd have to create a fluid mix and then create a local initial condition region of 100% of the 1 fluid and the rest 100% of the rest. i'm pretty sure they will just mix unless you play with the heat transfer properties. (See the kb on mixing in flow)
Hi Jared, I`m trying to predict the displacement of a fluid by another one and how long is the mixing zone to determinate the optimal flow rate. It's an habitual process when you send the oil since the tank. If you don't have a correct flow rate the mixing zone can be very long.
I don't know how créate a zone of a pipe only with oil and another one with wáter.
zone > you can use a local initial condition
