摘要

采用FLUENT离散相模型对环境室内水滴的蒸发过程仿真模拟.研究了喷入液滴直径、送风速度和送风温度对环境室内流场、湿度场的影响.计算结果表明:喷入液滴直径越小、送风温度越低时

湿度场的均匀性越好; 增大送风速度

湿度场能更快达到稳定.综合考虑经济性和湿度场均匀性

对于该计算模型

在送风温度为320 K、送风速度为18 m/s时得到最优的液滴直径为10 μm; 在送风温度为320 K、液滴直径为2 μm时得到最优送风速度为18 m/s.

Abstract

An efficient computational fluid dynamics(CFD)software

FLUENT

was employed for the simulation of evaporation process of water droplets in an artificially created environmental chamber with the discrete model. The flow and humidity fields in the chamber were investigated individually under various droplet diameter

inlet temperature and velocity. In the discrete model

the simulations of coupling particles with air were conducted using Lagrangian equation. The calculated results indicate that humidity meliorates with decreasing inlet temperature and droplet diameter. Moreover

the stabilizing time of the humidity field in the chamber is dependent on the inlet velocity. The humidity field becomes steady more easily with the increasing inlet velocity. In addition

in the chamber the optimal droplet diameter is 10 μm at an inlet temperature of 320 K and a velocity of 18 m/s

and the optimal inlet velocity is 18 m/s at an inlet temperature of 320 K for a droplet diameter of 2 μm.
