Abstract:In this paper, the growth and falling process of a single droplet in saturated steam is studied via the lattice Boltzmann method. The propagation of temperature field and flow field are directly simulated and the mechanism of heat and mass transfer is discussed. Moreover, the effect of relative velocity between droplet and steam on the growth and falling process of the droplet is also simulated. The results indicate the mean temperature of droplet with vertical velocity of steam is highest, while that with horizontal velocity is lowest. Furthermore, better condensation effect of droplet is obtained with smaller velocity of steam. (C) 2016 Elsevier Ltd. All rights reserved.
