【摘要】 对超音速汽-液两相流升压加热装置混合腔内汽-液两相温差的变化规律进行了初步实验研究。研究表明,由于汽-液两相流直接接触换热过程存在热阻,两相之间存在明显的温差。该温差随引射率增加而增加,但当引射率大于某一数值后则基本不变;在某一临界的质量流速下该温差达到其最小值。这些结果具有较大的理论和应用价值。更多还原

【Abstract】 An primary experimental research on the temperature difference between the phases has been performed in the super-sonic steam and liquid two phase flow in the steam inject. As the thermal resistance in the direct contact heat transfer between steam and cool water, there exists obviously the value of temperature difference. It increases with the flow ratio of water to steam, but keeps constant while the flow ratio is greater than a specific value. It reaches its minimum value at a critical mass flow rate. The results are both theoretically and practically valuable.更多还原
