Modelling the spray and combustion processes in diesel engine using coupled Euler-Eulerian and Euler-Lagrangian approach

The focus of this paper is to show that the existing and developed models are capable for describing spray formation, combustion and pollutant formation processes. The Euler- Eulerian approach was used for the spray modelling where the mathematical models of fuel jet disintegration and droplet evaporation are used. Spray combustion is modelled using the common Euler-Lagrangian approach. The coupling of two approaches have been performed by running simultaneous computations on separate computational domains with constantly exchanging mass, enthalpy and momentum sources. This research outlines the capability employing the coupled approach. The calculated results were compared with the available experimental data. It is concluded that the pressure and temperature evolution, combustion process and the emissions trends are well described using this approach. The coupled simulations could be used in further engine development retaining the high CPU efficiency taken from the Euler- Lagrangian simulations with an increased solution accuracy in the near-nozzle region employing the Euler-Eulerian approach.
