アニュラー型回転ヒートパイプの水平姿勢における作動液流動と熱輸送特性 : 第1報,作動液蒸発域の流動形態と熱輸送量

The flow pattern of liquid in an annular tube rotating around the horizontal axis is vizualized experimentally as the flow simulation of working fluid in a heat pipe. Correlations between volume ratio of heat medium and the critical rotation speed for the rimming or collapsing phenomena are obtained. After that, the heat transfer rate of the heat pipes are measured and it is shown that the transitional rotation speeds for the heat transfer agree well with those for the flow pattern.
