Abstract

A synthesized spheroid particle (SSP) method is proposed on the basis of the first principles of fluid dynamics for calculating consistently the atomization behaviors of spray droplets and liquid sheets injected, the mixing of air and fuel, and the wall-impingement of droplet. The method includes a formulation for evaluating the collision of droplets accurately. The atomization process of the conical sheet of liquid fuel injected from a simplex nozzle is simulated by the SSP method for a wide range of back pressures and initial cone angles.
