Research on the Optimization Helix Angle of Double-Helical Baffles Heat Exchangers

Abstract:

To investigate the relationships between heat transfer coefficient and baffle helix angle of double-helical baffles heat exchanger, the physical and mathematical model of double-helical baffles heat exchanger with different baffles helix angle were developed and carried out. The researched results show that the optimization baffles helix angle results in the highest heat transfer coefficient of double-helical baffles heat exchanger; the inlet flow flux of shell side has no effect on the optimization baffles helix angle for those heat exchanger with same heat transfer structure; The optimization baffles helix angle tends to decrease with the tube diameter increment of double-helical baffles heat exchanger.
