摘要
对甘油水溶液-空气两相混合物在TEMA-F型换热器壳侧的换热特性进行了研究,较系统地考察了气相折算速度、液相折算速度及流型对换热的影响.用加强模型对分层流、间歇流和环状流各流型区拟合了实验数据,得到了相应的关联式,可供此类换热器参考.
Systematic studies of heat transfer on the shell - side of a horizontal TEMA - F heat exchanger were carried out using glycerine - water solution and air mixtures. The effects of gas flux, liquid flux as well as flow pattern on heat transfer were studied in detail. The experimental data on stratified flow, intermittent flow and annular flow were correlared by using an enhancement model. The obtained heat transfer correlation can be recommened for design purpose.
