摘    要:本文采用1/3混合取平均值,牛顿迭代的方法在外界压力P=100~2 500kPa,外界温度T_∞=300~2 000K的范围内,首次对水滴在静止空气中的蒸发进行了数值计算,获得了水滴的湿球温度,蒸发常数,并把计算结果与文献中燃料液滴的蒸发常数进行了比较。

关 键 词:水滴  蒸发  湿球温度  蒸发常数

Abstract:By using a method of one third mixing with average value being taken and Newtonian iteration the numerical calculation of water drop evaporation in still air has been conducted for the first time within the range of outside pressure p=100-2500 kPa and ambient temperature T=300-2000K. Obtained are the water drop wet bulb temperature and evaporation constant. The results of calculation were compared with the evaporation constant of fuel liquid drop given in a published paper.
Keywords:water drop evaporation  wet bulb temperature  evaporation constant  numerical calculation
