A 3D Eulerian model to improve the primary breakup of atomizing jet

摘要: A 3D Eulerian model has been developed to improve the primary break-up of an atomizing jet. The is divided in three parts and implemented a modified version KIVA II. first part focuses mainly on liquid dispersion, second process itself, third adaptation model's mathematical formulation physics flow. Since spray close injector dense, thus chosen. However, when diluted, Lagrangian should then be applied. Different computations have carried out using this new will thoroughly discussed paper. calculation serves as validation model. Those which follow demonstrate importance internal flow inside development. They also manifest influence air-co-flow, assists atomization spray. Last but not least, we observe appropriate trends from pressure increased combustion chamber. ensemble these calculations displays principal advantage such model, enables us development upon entry into chamber, other words, during entire process- both after secondary break-up. Beyond point, no more initial cone angle nor droplet size distribution are further mandatory.
