- Abstract:
- The shell-and-tube heat exchanger with longitudinal fluid flow in shell side was selected as the re-search object. The characteristics of fluid flow and heat transfer in shell side of shell-and-tube heat exchangerwith a ribbon support structure were studied numerically.Based on the characteristics of fluid flow and heat-transfer in shell side of heat exchanger,the periodic unit duct model was presented and adopted in the numeri-cal calculations for heat exchanger. The detailed information of the fluid flow and temperature field were ob-tained. The thermodynamic characteristics in shell side of the ribbon support structures with different parame-ters were analyzed comprehensively. In addition,the characteristics were compared with that of rod baffle heatexchanger,another heat exchanger with longitudinal fluid flow in shell side. lt is concluded that in the samecondition,in shell side with a ribbon support structure,fluid is of bigger turbulent intensity,which enhancesheat transfer.
