Hi everybody,
I'm Senén a new user on OpenFoam and i'm trying to simulate a primary breakup of liquid jet with swirling flow at the inlet of the nozzle (s. Abb. 1). The domain consists of a parallelepiped (15x15x45mm), wich represent the fourth part of a nozzle. The simulation goes on with interFoam. I got results from t=0s to t=10s with the profil of the jet already developed at the outlet from the nozzle (s.Abb. 2). Abb.2. up: velocity profile at t=0s; down: alpha.water at t=0s. However i want to get a simulation with the complete development of the jet from t=0s at the inlet until t=10s at the outlet from the nozzle. I thing something is wrong with the inital and boundary conditions. The Mesh its ok and i got any error as long as the simulation is running. Attached the used files 0, constant and system. Do you habe some idee about the correct inital and boundary conditions for the liquid jet? Thank you, Senén |
