G0805 Visualization of Superfluid Turbulence Motion Using Fine Hydrogen Particles

Abstract

Superfluid helium has peculiar turbulence structure, superfluid turbulence, which is dominated by quantized vortex. Particle seeding visualization method is applied to this flow. The point of issue in this study field is that the particles motion mode difference. It is considered that the mode difference depends on the condition of particle-quantized vortex interaction and some particles motion models are introduced and experimental verification is required. In our study solid hydrogen is selected as tracer particles. We built fine hydrogen particles seeding system. This paper introduces our seeding method and image of hydrogen particles in HeII.
