Description
The goal of this project is an appropriate modeling of flash evaporation of cryogenic liquids. The proposed study will focus on the area located downstream of the nozzle where bubble formation in the superheated liquid leads to a rapid expansion and subsequent formation of droplets. Various direct numerical simulations (DNS) of simple, generic configurations will be used to improve modeling of the expansion process. The sensitivity of the results of different parameters such as Re, We and Ja-number will be tested and taken into consideration for the model formulation. The model should be used in the third period as a sub-grid model for large-eddy simulations (LES) of the whole process.
