While the actual jet inflow is much smaller than the mesh, the additional jet area at the inlet allows for entrainment of air near the inlet, and radial dispersal of the fluid into the surroundings as X increases.
The geometry and mesh have already been created, and can be read directly into Fluent as case and data files. Download them here. This tutorial will focus on the analysis of laminar and turbulent jets, and specification of the turbulent k-epsilon model.
Once you have downloaded the files, open Ansys Fluent. Select double precision and the 2D case (the case and data files cannot be read in if you select the 3D case).
