Hi I ran a 2D and 3D simulation for multiphase eulerian water jet flow. How come I am experiencing such a difference in velocity drop in the jet axial direction in the 3D case as compared to the 2D case. I have used the same simulation parameters for both 2D and 3D case.November 11, 2020 at 10:54 amRobAnsys EmployeeCheck the mesh resolution in the axial direction, it's invariably too coarse as you move away from the nozzle. Look up adaption to avoid needing to remesh. For 2d v 3d, in 2d you're modelling a plane, so there is no dispersion in the third dimension as you're modelling a slot. In 3d you have air entrained from all around the jet: have a look at axi-symmetric for the 2d case. nViewing 1 reply thread
