A Lagrangian Collision Model Applied to an Impinging Spray Nozzle 2006-01-3331
This paper describes the implementation and evaluation of a collision model for CFD spray simulations. The collision model is intended to be used for prediction of fuel sprays from specially designed impinging spray nozzles.
The new model is enhanced in terms of collision frequency, post-collisional characteristics and collision induced break-up. The model is evaluated in terms of macro scale properties, such as spray penetration and spray cone angle.
