火花产生的气泡是实验室规模的水下爆炸（UNDEX）气泡动力学模型的强有力的候选人，因此，很好的数据来源，用于验证模拟工具。与涉及爆炸物的实验相比，它们的相对安全性、清洁性和紧凑性使得能够以相对较低的成本对气泡动力学进行高质量的观察。本文讨论了火花产生气泡的相关优点，重点是再入射流可视化。它还解决了缩放问题和关注的能量沉积到气泡作为放电过程的结果。总之，一个程序指定使用火花产生的气泡作为实验室规模的模型UNDEX气泡动力学和数据验证的模拟工具。
Spark-generated bubbles are strong candidates for laboratory-scale models of underwater explosion (UNDEX) bubble dynamics and are, therefore, excellent sources of data for validation of simulation tools. Their relative safety, cleanliness and compactness enable high quality observations of bubble dynamics at relatively low cost compared to experiments involving explosives. This document addresses the relevant advantages of spark-generated bubbles, focusing on re-entrant jet visualization. It also addresses scaling issues and concerns about the deposition of energy into the bubble as a result of the electric discharge process. In conclusion, a procedure is specified for using spark-generated bubbles as laboratory-scale models of UNDEX bubble dynamics and as data for validation of simulation tools.
