Revisited Model for Supercooled Large Droplet Impact onto a Solid Surface

Résumé

A rationally based methodology is proposed to derive a new mass loss empirical model for supercooled large droplets. The numerical results from the ONERA two-dimensional trajectory solver and the experimental results from the NASA Papadakis supercooled large droplet database are combined to get both the impinging and the deposited mass flow rates at each point of the test model. These data are used to derive a new model for the collection efficiency. It allows clearly separating the influence of the kinetic energy, which is the dominating effect close to the leading edge, from the influence of the angle of incidence, which is the most influent parameter close to the impingement limits. Moreover, the model can be used for both supercooled large droplets and small droplets.
