Abstract (VO)
Résumé

Large Eddy Simulations of a plane turbulent impinging jet have been carried out using the dynamic Smagorinsky model. The statistical results are first validated with the measurements from the literature: mean and turbulent quantities along the jet axis and at different vertical locations are presented. This study is completed by the analysis of the wall shear stress at the impingement wall. The effect of the jet Reynolds number (3000⩽Re⩽13500) on the kinematic development of the jet is also discussed.

Une étude par simulations des grandes échelles turbulentes a été menée sur un jet plan turbulent en impact proche. Les résultats statistiques sont, dans un premier temps, validés par rapport aux mesures de la littérature : les grandeurs moyennes et turbulentes le long de l'axe du jet et à différentes positions verticales sont présentées. Cette étude est complétée par une analyse de la contrainte de cisaillement pariétal. Enfin, l'effet du nombre de Reynolds du jet sur le développement cinématique du jet est également discuté.
