Abstract:
The experimental results of the heat transfer and pressure drop performances of trisection baffled helix heat exchangers with inclined angles of 10°, 15° and 20°(sector baffles), 15°(ellipse baffles), and 20°(overlap sector baffles)are presented. As a compassion scheme the results from a segmental baffled heat exchanger are also provided. The results show that the scheme with 20° sector baffles inclined angle has the highest shell side heat transfer coefficient and low pressure drop; the scheme of axial overlap baffled helix heat exchanger is not reasonable; the decisive factor to the performance is the equivalent helix angle. The correlation equation is obtained including inclined baffle angle correction factor for shell-side heat transfer coefficient of trisection baffled helix heat exchangers, and the deviation errors between the majority of the results of both calculation and experiment are less than ±10%.
