A novel methodology to simulate fuel injection in multipoint systems - Application to liquid jet in crossflow
Résumé
A novel strategy to build lagrangian injectors for spray injection in disperse phase computations is proposed. These injectors can reproduce the spray state (injection location, flow rates, droplets sizes and velocities) extracted from resolved atomization simulations performed with a sharp-interface approach (ACLS/GFM) [1]. The application case is a high-pressure, non-reactive kerosene jet in crossflow (JICF) atomizer configuration [2]. Resolved simulations of atomization for this configuration are performed and validated with the experimental correlation for the jet trajectory. The models learn the spray from these simulations and process it to create spatially distributed injectors for lagrangian droplets injection. Finally, the models are applied to the same configuration and compared to experimental data.
