Computational Modeling of the Atomizing of a Gas Stream from a Pneumatic Nozzle
Atomizing of liquid is widely used in modern technology. Atomizing occupies an extremely important place in power engineering, when burning liquid fuels. In this work provides verification of the method for modeling the atomizing of a gas-liquid stream from a pneumatic nozzle. Primary atomization is modelled using Large Eddy Simulation model (LES) and The Volume Of Fluid model (VOF). The results of the calculations show an acceptable agreement with experiment on the main characteristics of the spray. The results of calculations can be very useful for estimations, since they allow qualitatively correct determination of the structure of a two-phase flow, parameters and shape of droplets, and the speed and direction of their motion, which in principle can not be obtained by other methods.
