Previous models concerning diesel spray are impossible to calculate micro-explosion process and combustion process of water emulsified fuel. My study constructed mesoscale discrete particle models to simulate complex motion of emulsified fuel particles. Two models were constructed； micro-explosion process model and combustion process model of fuel droplet. These models based on cellular automata model which has a feature of both time and space discretization. Micro-explosion model simulates the microparticulated motion of vapor explosion. Furthermore combustion model can trace the combustion process of each microparticulated fuel droplet. My results show that emulsified fuel droplets burned rapidly rather than normal fuel droplets. Although these are simple models, it is thought that my models will be the base model to consider water emulsified fuel combustion theoretically.
