Numerical simulation of impinging spray characteristics under high ambient pressures with an improved droplet collision model

Impinging spray characteristics under high ambient pressures (10–60 atm) were investigated experimentally and numerically. A recently proposed pressure-dependent droplet collision model was adopted to determine the collision outcomes. The results being compared to the predictions of Estrade et al. and O’Rourke’s droplet collision models. The comparison shows that the present pressure-dependent model accounts for the previous experimental...
