The flow structure of a thermal counterflow jet in helium II.

Summary

The temporal and spatial variation of the normal-fluid velocity was measured with a laser Doppler velocimeter in order to investigate the detailed nature of the helium II thermal counterflow jet. The velocity profile and the variation of the center-line velocity with the axial distance are also obtained to discuss the flow structure in a downstream region. It was found that the thermal counterflow jet in the far field behaves like a fully-developed turbulent jet in ordinary fluids. It, however, seems that the way of development differs from that of ordinary fluid jets.
