Abstract

This paper presents a numerical investigation of a round jet using a synthetic method to generate some free-stream turbulence into the jet core. Besides, this work also aims at evaluating the added advantage of the use of high-order numerical schemes—namely the AUSM+P spatial scheme with MUSCL extrapolation of the 3rd and 5th order—for this type of simulations. Academic test cases are presented to illustrate the main properties of the numerical methods used, then the Zonal Detached Eddy Simulation (ZDES) of a round jet is scrutinized with an emphasis on the influence of the injected synthetic turbulence.
