- Summary:
- The ideology behind the project is to alter the helical angle of the baffles attached to the heat exchanger such that itincreases the velocity of the flow of high viscous fluids. Investigations of thermo-hydraulic performance wereconducted on five trisection helical baffle heat exchangers with different inclination angles, baffle shapes, orconnection patterns, and one segmental baffle heat exchanger (SEG). A comparative analysis of three sector baffleschemes with inclination angles of 10° (10°S), 15° (15°S), and 20° (20°S); an ellipse baffle scheme with an inclinationangle of 15° (15°E); and an axial overlap sector baffle scheme with an inclination angle of 20° (20°D) was performed.Local images were constructed to obtain pressure loss characteristics and flow field distributions. The flow fieldcharacteristics, such as the Dean vortex secondary flow and bypass leakage between adjacent baffles, are clearly shownand discussed. The same inclination angle schemes have completely different properties because of the baffle shapes orconnection patterns. The performance of the end-to-end scheme is superior to that of the axial overlap scheme, and theellipse baffle scheme is inferior to the sector baffle scheme. The 20°S scheme has the optimum comprehensive indexand lowest shell-side pressure loss. The 10°S scheme has the highest shell-side Nusselt number and shell-side pressureloss, and can be selected only when heattransfer capability is very important in an engineering application
