Sažetak
The liquid Diesel fuel is usually injected into the combustion chamber by using an injector as atomizing system. The Injected liquid fuel disintegrates into numerous droplets that penetrate into the combustion chamber. This process, called atomization, involves primary break-up of the liquid core followed by secondary break-up. Primary break-up occurs in near nozzle region while secondary break-up occurs in the downstream spray zone. The understanding of the spray process is of significant importance for emission prediction. This poster shows the comparison of two common models used for spray calculation – Eulerian Eulerian and Eulerian Lagrangian model. Also, use of coupled simulations is shown. Coupled simulations combine advantages of each spray model and they are used for calculation of spray, combustion and emission in IC engine.
