- Description of a Eulerian–Lagrangian Approach for the Modeling of Cooling Water DropletsPublication . Meireles, Rúben D. S. O.; Magalhães, Leandro; Silva, André; Barata, Jorge M MThe 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.
