Data underlying the quantification of re-entrant jet in a cavitating axisymmetric venturi

Using tomographic particle image velocimetry, we visualise and quantify the near-wall re-entrant liquid jet velocity below the vapour cavity in an axisymmetric venturi. The aim of this work was to decipher the exact role of the re-entrant jet in cavity detachment leading to cloud shedding. The full details of the study can be found in the underlying publication. This dataset will help researchers for the validation of their numerical models aimed at simulating partial cavitation.

本研究采用层析粒子图像测速法（tomographic particle image velocimetry），对轴对称文丘里管内蒸汽腔下方近壁面回流液射流的速度进行可视化与量化分析。本研究的核心目标在于厘清回流射流在引发云状空化脱落的腔体脱离过程中的确切作用机制。本研究的完整细节可参见所附的正式发表文献。本数据集可用于辅助研究人员验证其用于模拟部分空化现象的数值模型。
