Abstract
This paper presents ZDES simulations of jets on industrial configure-tions, taking into account the turbulent flow rate coming from the engine. The strong influence of this turbulent ratio on the jet development has already been demonstrated in previous researches and it has to be taken into account for such realistic simulations. Hence, a turbulent flow generator module for LES-like simulations was first developed and validated. Next, studies on industrial double flux configurations are presented and compared with dedicated experiments. The results show that the ZDES simulations presented are in a very good agreement with measurements and the averaged mean and turbulent results into the jets are properly predicted thanks to the turbulent flow generation technique.
