多组螺旋叶片折流板换热器性能试验研究

摘要

The test of heat transfer performance was carried out in five the spiral blade baffles heat exchangers, and their shell heat transfer and pressure drop were compared. Through analysis and regression calculation of experimental data, experience formulas of shell-side heat transfer coefficient and pressure drop were obtained. This result could provide a reference for numerical simulation and design of spiral blade baffles heat exchangers.%　　进行了5组参数下螺旋叶片折流板换热器传热性能试验，对比壳程传热和压降性能，并对试验数据进行回归计算，获得其壳程传热系数和压力降的经验计算公式。结果可为螺旋叶片折流板换热器系统模拟和设计计算提供参考。
