In this paper, we investigate the evaporation mass flow originating from spills of gas-oline. Large spills of gasoline may form during partial or complete roof sinkings or inthe case of perforations at various deck fittings at external floating roof tanks usedfor the storage. Additionally, spills may form in the retention area in the case of leak-ages at pipes or at the hull. The aim is to predict the order of magnitude of real-scaleevaporation mass flow. The determined evaporation mass flows will be used in arelated project as input values for subsequent dispersion modeling in the vicinity ofthe tanks. This is relevant for questions of fire and explosion protection as well as forenvironmental protection aspects in tank farms or refineries, which use externalfloating roof tanks. The measurements presented in this paper were compared withpredictions by empirical models and investigations of evaporations from small floorspills, round-bottom flask, or from Petri dishes published in the literature. The maingoal of this paper is to test the applicability of empirical models to provide reasonableevaporation mass flows as input for CFD dispersion simulations.

汽油泄漏的初始蒸发质量流量的实验测量以及与经验模型的比较

在本文中，我们研究了源自汽油溢出的蒸发质量流。在部分或完全屋顶下沉期间或在用于储存的外浮顶罐的各种甲板配件处穿孔的情况下，可能形成大量汽油溢出。此外，在管道或船体泄漏的情况下，可能会在保留区域形成溢出。目的是预测实际规模蒸发质量流量的数量级。确定的蒸发质量流量将在相关项目中用作输入值，用于随后在储罐附近进行扩散建模。这与使用外浮顶储罐的储罐区或炼油厂的防火和防爆问题以及环境保护方面的问题相关。本文中提供的测量结果与通过经验模型和对小地板溢出物、圆底烧瓶或文献中发表的培养皿蒸发的研究的预测进行了比较。本文的主要目标是测试经验模型的适用性，以提供合理的蒸发质量流量作为 CFD 扩散模拟的输入。
