Effervescent Spray Modelling: Investigation of Drop Momentum Models and Validation by Measured Data

Original language description

The use of effervescent atomizers is constantly rising and therefore the need to develop and validate appropriate models is increasing as well. The main goal of this paper is to investigate an effervescent spray model for combustion simulations. In the first part of the paper is described the spray measurement experiment along with the used measuring techniques. In the second part Euler/Lagrange approach is adopted for the two-phase flow simulations and the selected models for primary and secondary breakup, droplet drag and collisions are briefly described. Primary and secondary atomization is evaluated in a computational isothermal spray experiment. Results show discrepancies in the prediction of radial evolution of Sauter mean diameter (SMD). Difficulties in predicting the formation of small drops are highlighted.
