Helical Baffle Thermohydraulic Performance Versus Segmental Baffle One

Résumé

In this contribution, we reworked the Bell-Delaware technique for a HB-STHX to systematically study its thermohydraulic performance behavior in the shell side. The helical baffles are continuous quadrant sectors with five inclination angles 25°, 30°, 35°, 40° and 45° and are exanimated for six different values of Reynolds number from up to 40 . We have observed an increase in global heat transfer rate while a decrease in pressure loss, in continuous helical baffle case compared to segmental one. we have found that the baffle inclination 40° has the largest heat transfer coefficient, 25° gives the lowest pressure drop, whereas 45°, the largest inclination we have used, displays the greatest performance evaluation factor.
