He4中颗粒-涡的相互作用和流动显示
Particles-vortex interactions and flow visualization in He4
摘要：
最近的实验表明，在实施和使用粒子图像测速（PIV）和粒子跟踪技术的研究在He 4湍流的显着进展。然而，在超流相的实验数据的解释需要了解示踪剂粒子的运动是如何受到两个组件，粘性正常流体和无粘超流。特别重要的是粒子与量子涡线的相互作用问题，量子涡线不仅可能强烈影响粒子运动，而且在某些条件下，甚至可能将粒子捕获在量子涡核上。本文回顾了最近的理论，数值和实验结果在这个快速发展的研究领域，把最近的结果，并解决明显的不一致。还讨论了一个密切相关的技术检测量子化涡旋负离子气泡在He 4。
英文摘要：
Recent experiments have demonstrated a remarkable progress in implementing and use of the Particle Image Velocimetry (PIV) and particle tracking techniques for the study of turbulence in He4. However, an interpretation of the experimental data in the superfluid phase requires understanding how the motion of tracer particles is affected by the two components, the viscous normal fluid and the inviscid superfluid. Of a particular importance is the problem of particle interactions with quantized vortex lines which may not only strongly affect the particle motion, but, under certain conditions, may even trap particles on quantized vortex cores. The article reviews recent theoretical, numerical, and experimental results in this rapidly developing area of research, putting critically together recent results, and solving apparent inconsistencies. Also discussed is a closely related technique of detection of quantized vortices negative ion bubbles in He4.
