Liquid Jet in Cross Flow Modeling Under Different Weber Numbers

Many applications employ liquid jet in cross flow (LJICF) configuration such as fuel spray in gas turbine combustion chambers, sanitizer spray subjected to airflow, agricultural sprays under wind conditions, etc. The Weber numbers (We) vary widely, and the model prediction across the range needs to be assessed. The present work investigates the modelling prediction for LJICF configurations by comparison with the available experimental data. Turbulence is modelled using the Reynolds Averaged Navier-Stokes (RANS) approach, and the discrete phase modelling is accomplished via the Eulerian-Lagrangian approach using a finite volume method-based solver. The primary breakup model used is cone injection, and the Madabhushi model is used for secondary breakup. The results for droplet size show good agreement at higher Weber numbers, while the model underpredicts the droplet sizes for low Weber number cases.
