摘要
研究了喷动流态化热砂冷却装置内部的气－固两相流动层的测温方法和温度分布，并对装置内部各区段的冷却特性和冷却机理进行了分析，指出了装置进一步改进的方向。
emperature measurement and distribution in laminar flow of gas-solid phase in cooling device of hot sand fluidization by jet has been work ed on.Cooling characteristic and mechanism in varies of sector of the device is analysed and further improvement pointed out.
