Abstract

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.
螺旋折流板与节段折流板的热水力性能比较
在这篇论文中,我们对HB-STHX的Bell-Delaware技术进行了重新设计,系统地研究了它在壳侧的热液性能行为。螺旋挡板是连续的象限扇形,有5个倾角25°、30°、35°、40°和45°,并可检测6种不同的雷诺数值,最高可达40。我们观察到,与分段式挡板相比,连续式螺旋挡板的整体传热率增加,压力损失减少。我们发现挡板倾角为40°时传热系数最大,25°时压降最小,而倾角为45°时性能评价因子最大。
