Comparison between interFoam and Fluent
Hi to all,
I obtained some strange results from my simulations. I tested this case:
At the initial time t = 0 the right wall of a closed tube completely filled with liquid is removed, allowing the liquid to exit the domain and, at the same time, allowing the gas to enter. The computational domain is a horizontal tube with diameter D = 0.0508 [m] and length L = 3.0 [m]. My aim is to calculate the velocity of the front of the bubble.
I obtained a fluctuating velocity while the same simulations, performed with Fluent, give me a constant velocity. Note that the velocity must be constant.
Is possible that the cause are parasitic current?
