Sažetak
The development of alternative fuels, such as lower cost refinery fuels, solar fuels, heavy fuel oils, represents one of the main directions of internal combustion engine research. These modern fuels require a new modelling framework capable of predicting their multi-component behaviour in engine-like conditions since droplet evaporation of such fuel involves physical processes which are significantly more complex than in a fuel that can be approximated by one component. Therefore, the topic of this research project is the development of a numerical model capable of predicting the dynamic behaviour of multi- component fuels in dense sprays. In the model, the method of classes will be used in the Eulerian framework, where each dispersed phase is characterised by its droplet size, velocity and concentration of components. In the current method, the poly-dispersed nature of the spray is handled using the method of classes in the Euler-Euler framework, where each dispersed phase is characterised by its droplet size and velocity. This approach treats every droplet class as a different phase in the calculation. Therefore, every size class has its momentum and continuity equation, but the mixture pressure is shared among all phases. The individual size classes undergo breakup and coalescence, which are implemented as mass source/sink terms in phase continuity equations and momentum source/sink terms in the phase momentum equation.
