Heat and mass transfer in the process of movement of water drops in a high-temperature gas medium

The heat and mass transfer in the process of movement of water drops in a high-temperature gas medium was numerically investigated. The regimes and conditions of formation of the zone of mutual influence of two drops were determined on the basis of an analysis of the temperature and concentration fields of the water vapor in the neighborhood of the trajectory of movement of the drops. The times of existence (complete evaporation) of one and two drops as a result of their interaction with the high-temperature products of combustion of a typical condensed liquid substance were compared. It has been established that only in the case where the distance between the two drops is small is the intensity of evaporation of water from them substantially lower than that of a single drop. © 2013 Springer Science+Business Media New York.
