This paper presents a tool developed in-house for modeling free-falling water droplet cooling processes, utilizing a two-way coupling model and stochastic separated flow technique. The study focuses on the interactions between water droplets and carrier fluid at different humidity ratios, with consideration for heat and mass transfer coefficients and vibrations.
The present paper describes a tool developed in-house for the modeling of free-falling water droplet cooling processes. A two-way coupling model is employed to account for the interactions between the droplets and the carrier fluid, following a Eulerian-Lagrangian approach. In addition, a stochastic separated flow technique is employed, involving random sampling of the fluctuating fluid velocity. In physical modeling, two empirical correlations are considered for determining the heat and mass transfer coefficients, with the possibility of accounting for vibrations. The numerical results indicate the preponderance of the interactions between droplet and carrier fluid at various humidity ratios.
