Bubble dynamics study of OME1 fuel droplet

As a clean alternative fuel it is necessary to understand the underlying mechanism of OME1 flash boiling. Here the aim is to study the bubble growth characteristics of OME1 in detail starting from heterogeneous bubble nucleation followed by bubble growth and rupture. Investigation will be performed under engine like operating condition (focus will be on early injection strategy during intake stroke where the chamber pressure is at sub-atmospheric level). Different level of superheat will be studied to investigate the main governing parameters (surface tension controlled, inertia controlled or heat diffusion controlled) influencing the bubble growth. Effect of system operating condition on different growth regime will also be discussed. At the end the coupling between external and internal surface boiling will be shown to highlight the importance of bubble dynamics in superheat fuel vaporization.
