The invention provides a method for calculating the oil leakage evaporation capacity in an open environment. The method comprises the steps of: S1, establishing oil evaporation model conditions, and completing parameter setting; S2, performing optimal calculation through a genetic algorithm, and calculating oil evaporation parameters; and S3, forming a continuity equation, a momentum equation and a multi-phase flow equation, and finally, forming an evaporation model. For the oil leakage evaporation characteristics in the open environment, the oil evaporation process is simplified; and, compared with an analytic approach model widely used at present, the constructed evaporation model accords with oil evaporation mechanisms better, and is high in precision and few in model parameter. 本发明提出了种在开敞环境中石油泄漏蒸发量计算方法，包括如下步骤：S1，建立石油蒸发模型条件，将参数设置完成；S2，通过遗传算法进行优化计算，对石油蒸发参数进行计算；S3，形成连续性方程、动量方程和多相流方程，最终形成蒸发模型。针对开敞环境石油泄漏蒸发特点，对石油蒸发过程进行了简化，所构建的蒸发模型比目前广泛应用的分析法模型更加符合石油蒸发机理，精度高且模型参数少。
