✦ Synopsis

In this paper, the influence of a macro-flow, which is some kind of natural convection caused by heat-in leak in rotational cryostats, has been investigated.

A cooling channel unit which has a main flow counter to the buoyancy direction has been made to simulate the macroflow influence. A high-speed camera have been used to observe the transient local convection. Also a thin fihn thermometer has been used to detect the transient temperature variation.

As the result, some fluctuation caused by the macro-flow has been observed in the transient convection . The degradation of the transient temperature variation and steady heat transfer have been measured.
