文摘
CFD simulation of unsteady wind-driven rain is performed based on LES. Influence of wind-flow unsteadiness on the behavior of raindrops is investigated. Surface wetting by large raindrops is mainly dictated by the large-scale motions. Small raindrops are mainly influenced by smaller local turbulent structures. Mean catch ratio values stabilize around a constant value after about 300 s.
