Knowledge of the droplet size distribution (DSD) from the Deepwater Horizon (DWH) blowout is an important step in predicting the fate and transport of the released oil. Due to the absence of measurements of the DSD from the DWH incident, we considered herein hypothetical scenarios of releases that explore the realistic parameter space using a thoroughly calibrated DSD model, VDROP-J, and we attempted to provide bounds on the range of droplet sizes from the DWH blowout within 200 m of the wellhead. The scenarios include conditions without and with the presence of dispersants, different dispersant treatment efficiencies, live oil and dead oil properties, and varying oil flow rate, gas flow rate, and orifice diameter. The results, especially for dispersant-treated oil, are very different from recent modeling studies in the literature.
了解深水地平线（DWH）井喷的液滴尺寸分布（DSD）是预测泄漏石油的归宿和迁移的重要一步。由于缺乏DWH事故中DSD的测量数据，我们在此考虑了一些假设的泄漏情景，这些情景使用经过全面校准的DSD模型VDROP-J探索实际参数空间，并试图给出井口200米范围内DWH井喷液滴尺寸范围的界限。这些情景包括有无分散剂存在、不同的分散剂处理效率、原油和老化油特性以及不同的油流速、气体流速和孔口直径等条件。结果，特别是对于经过分散剂处理的油，与文献中最近的建模研究有很大不同。
