Computation Validation on Lateral Jet Interactions at Supersonic Speeds

Kurzfassung

The objectives of the present Action Group on “Lateral Jet Interaction at Supersonic Speeds” is to deeply analyse the effect of the hot-gas jet by the use of CFD simulations. At the end, the main goal is to define the most appropriate similarity parameters for wind tunnel tests using cold gases. Experiments from DLR Cologne and ONERA/MBDA-France on generic missile models are used in order to achieve numerical simulations of the interaction between a lateral jet and a supersonic cross flow of a missile. These experiments using either a cold-air jet or a hot-gas jet, the latter produced by the combustion of propellants, are well documented and the data are used for the validation of the numerical simulation using either an ideal gas or a multi-species fluid, respectively. The objective of the present work is only the validation of the numerical simulations by comparison with the DLR and ONERA/MBDA-France experiments with cold-air and hot-gas jets. The AG members use the same computational meshes for the comparison of the numerical results got from different CFD codes solving 3D, viscous, turbulent, RANS computations.
