Modeling of gasoline spray impingement

WebThis paper compares several linear‐theory‐based models for droplet shattering employed for simulations of spray impingement on flat wall surface or a circular cylinder. Numerical simulations are conducted using a stochastic separated flow (SSF) technique that includes sub‐models for droplet dynamics and impact. WebThis paper is concerned with aspects of gasoline spray droplet impingement simulation, for which an improved model has been developed for predicting the outcomes of spray …
