Atlauncher divergence8/5/2023 The jet development shows significant improvement compared to similar past simulations. The flow field appears to agree with the expected turbulence behavior and the available experimental data. Both a refined grid and a geometrical boundary layer tripping in the convergent are used to get highly disturbed turbulent conditions at the nozzle lips. The full convergent-divergent nozzle is explicitly included in the computational domain thanks to the unstructured flow solver. The resulting noise is propagated in the far field by solving the full Euler equations with a high-order discontinuous Galerkin method on unstructured grids. A Mach 3.1 overexpanded hot jet is computed via a large-eddy simulation by solving the filtered Navier-Stokes equations with a finite volume method on unstructured grids. Based on appropriate metrics, a good agreement with the experiment is obtained.Ī procedure to accurately simulate a free hot supersonic jet and its associated noise, which uses simultaneously a turbulence tripping method and a two-way coupling between a flow solver and a nonlinear acoustic solver, is proposed in this study. Nonlinear propagation effects, natively taken into account by the full Euler solver, are finally highlighted and discussed. A more careful analysis of the pressure field suggests that the noise is strongly influenced by the flame trench geometry. The aerodynamic and acoustic results are compared to a previous computation involving the Ffowcs Williams and Hawkings approach and show a better agreement with the measurements conducted at the MARTEL facility. This methodology relies on a large-eddy simulation of the jet and the acoustic near field, associated with a full Euler simulation of the acoustic far field. The computation is performed with a two-way coupled approach on unstructured grids. An over-expanded Mach 3.1 hot jet entering a flame duct where it impinges on a deflector before being guided in a horizontal duct is considered. Available for Forge, Fabric and Quilt.This study aims to numerically investigate the noise radiated by a reduced-scale rocket engine jet at lift-off conditions including a flame trench.
