壳程螺旋扭片强化传热研究

Research on the enhancement of heat transfer by helical ribbon in the shell side

通过在管壳式换热器壳程插入螺旋扭片 ,进行了壳程流体纵向冲刷型横纹槽管管壳式换热器的传热及流体阻力实验 。

An experiment is made in the heat transfer and resistance of transverse fluted tube heat exchanger with longitudinal erosion on sheath by inserting a helical ribbon into the shell side of a shell and tube heat exchanger Influences of the helical ribbon in the shell side on the heat transfer are analyzed
