摘要 设计了一种新型插入扰流元件管式换热器,并依据相关文献的模拟数据将其与波纹管、光管在不同流速下的管内壁面平均传热系数、换热量、平均Nusselt数以及摩擦阻力的变化特性进行了分析比较。结果表明:插入扰流元件换热管在强化换热能力的同时其压力损失也会很大,所以在实际应用过程中选取插入扰流元件换热管时一定要考虑其经济性;在泵功率消耗一定时,插入扰流元件换热管的热效率与波纹管的热效率很接近。但插入扰流元件换热管在制造工艺上具有加工方便、固定灵活等优点,比较适合对现有换热器的改造。所以,该种热管同样具有广泛的应用价值。 设计了一种新型插入扰流元件管式换热器,并依据相关文献的模拟数据将其与波纹管、光管在不同流速下的管内壁面平均传热系数、换热量、平均Nusselt数以及摩擦阻力的变化特性进行了分析比较。结果表明:插入扰流元件换热管在强化换热能力的同时其压力损失也会很大,所以在实际应用过程中选取插入扰流元件换热管时一定要考虑其经济性;在泵功率消耗一定时,插入扰流元件换热管的热效率与波纹管的热效率很接近。但插入扰流元件换热管在制造工艺上具有加工方便、固定灵活等优点,比较适合对现有换热器的改造。所以,该种热管同样具有广泛的应用价值。
