Abstract
The work presented in this paper is a first attempt at tracing both the vaporization droplet his-tory and the momentum exchange between the liquid and gas phase, in a reacting flow field exposed to acoustic propagation waves. The liquid phase is tracked with a Lagrangian ap-proach, while the carrier gas phase is modelled in an Eulerian framework, based in a two-way coupling interaction, under the main assumptions of dilute regime and infinite thermal con-ductivity. Acoustic propagating waves will eventually affect the combustion dynamic due to oscillating heat released by the flame. Aim of this work is to assess a strategy to estimate the effect of an oscillating gas velocity field on: droplet displacement, redistribution of the char-acteristic droplet diameters, changes in the evaporation rate. Assuming the hypothesis of di-lute regime as valid, the study is carried out by means of a non-dimensional number charac-terization.
