The discussion revolves around the application of the Bernoulli equation in the context of fluid flow through a pipe with a parallel branch. Participants explore how flow establishes in scenarios involving changes in pipe diameter and the effects of head loss due to friction.
Participants express various viewpoints regarding the behavior of flow in the described scenarios, with no consensus reached on how the flow will establish or the implications of introducing the branch. Multiple competing views remain on the effects of pressure and head loss in the system.
Participants acknowledge limitations in their assumptions, particularly regarding the effects of friction, the geometry of the pipe system, and the conditions under which the Bernoulli equation applies. The discussion highlights unresolved mathematical steps and the complexity of flow behavior in the presence of parallel branches.
Ideally, I would stretch this system out horizontally to allow the flow to fully develop in each section too.axim said:With an external tool like Paraview it should be possible, but I've never used it so far and it's rather complicated. At least I didn't manage to do it yet and would need some time to learn it first (it's not as intuitive as I hoped). If anybody is experienced enough I could upload the measurement data, though.
