Artigo Completo:

Jet flow has several industrial applications like jet pumps, burners, ejectors as well as process safety. This work investigates square and axisymmetric free jet in order to verify the impact in the velocity profile. The geometry was built on ICEM software and discretized using unstructured mesh. The governing equation were solved numerically applying the finite volume method using upwind scheme for convective terms and central differentiation for diffusion terms. Initial results show that axisymmetric and square orifices have very similar free jet. This is not in accordance with the current understanding of high aspect ratio jets. On the other hand, the jet centreline decay is qualitatively well represented. Further investigation concerning the influence of mesh type and size is demanded.
