Calculation of evaporation is needed in many applications including swimming pools, water reservoirs, nuclear fuel pools, pools for rejection of heat from refrigeration systems, process tanks, etc. Hence accurate methods for prediction of evaporation are needed. Many prediction methods have been published including analytical models and empirical correlations. In the present study, 18 published prediction methods are compared to a very wide-ranging database which includes data from laboratory scale studies, swimming pools, and fuel pools in nuclear power plants. The data are from 25 sources. The range of data includes air temperatures from 6°C to 200°C, water temperatures from 7.1°C to 94.2°C, relative humidity from 0.21% to 98%, and air velocity from 0 to 8.5 m/s. The accuracy of prediction methods is examined for conditions in which natural convection dominates, that in which forced convection dominates, and that in which natural convection is absent. The results are reported and discussed. Recommendations are made for application.

许多应用中都需要计算蒸发，包括游泳池、水库、核燃料池、制冷系统散热池、工艺罐等。因此需要准确的蒸发预测方法。许多预测方法已经发表，包括分析模型和经验相关性。在本研究中，18 种已发表的预测方法与一个非常广泛的数据库进行了比较，该数据库包括来自实验室规模研究、游泳池和核电厂燃料池的数据。数据来自 25 个来源。数据范围包括 6°C 至 200°C 的气温、7.1°C 至 94.2°C 的水温、0.21% 至 98% 的相对湿度以及 0 至 8.5 m/s 的风速。在自然对流占主导地位、强制对流占主导地位和没有自然对流的情况下，检查预测方法的准确性。报告和讨论结果。提出申请建议。
