| Description | No/ Break-up of droplets occurs while most of their mass is still in liquid phase. A computational method has been developed to simulate the deformation and evaporation of fuel droplets. The method -due to extremely high computational cost- was used to simulate the movement of a single droplet in high pressure conditions. The results were tested against existing experimental studies. The comparison of experiments and simulations showed that the computational methods successfully reproduce the experimental results, regarding. the evaporation rate of the droplets and the change of their shape. The most important finding was that the break-up of the droplets in these conditions occurs very soon, when a very small fraction of the droplets mass has evaporated. |
| Exploitation Route | As experiments in the simulated conditions are not available and hard to be conducted due to technical limitations, the results of the simulations performed for one droplet can be used for the modelling of sprays. |
