Experimental and Numerical Analysis of a Multi- Injection IC Engine
In this paper, two spray modelling approaches were used: the Euler Lagrangian spray modelling approach which is the conventional approach for simulating various engineering applications, and the Euler Eulerian approach commonly used to describe physical processes occurring in the near-nozzle region with a higher accuracy. The combustion of vaporised fuel was described with the implemented chemical mechanism. The conducted research showed that the evaporated fuel predicted with the Euler Eulerian approach is more pronounced in the dense spray region, which was not captured with the Euler Lagrangian modelling approach. In the nozzle region, the Euler Eulerian approach showed a more intense cooling of the gas phase. Such behaviour could be addressed to the differences in the modelled evaporation rate, indirectly determined with the fuel atomization. Also, the results showed that the impact of the swirl motion on the in-cylinder pressure could be neglected in both spray modelling approaches for the observed operating point. Finally, the results such as the mean pressure, mean temperature and rate of heat release are found to be in good agreement with the experimental results for both modelling approaches.
