Review of Improvements on Shell-and-Tube Heat Exchangers With Helical Baffles

A review of the advancements made in helical baffles used in shell and tube heat exchangers

“…DCHB manufacturing is easy as compared to CHB. So, DCHB are more profitable and feasible than CHB [27,30]. The values for the graph in Fig.…”

“…Moreover, they showed that pressure drop was less in helical STHE as compared to segmental ones while heat transfer rate is higher for segmental baffle STHE but overall performance of helical baffle STHE (HB-STHE) is better than segmented baffle-STHE (SG-STHE) [27,28]. If segmental and helical baffles are compared for use in STHEs, helical baffles serve as a more promising technology because of having less shell-side pressure drop, better heat transfer performance, less fouling and less fluid-induced vibration [29][30][31][32]. The following graph shows the comparison of segmental baffles to helical baffles (Fig.…”

Introductory Chapter: Advanced Features and Applications of Heat Exchangers–An Outline

“…In the paper by Wang et al [14], a general review was provided on developments and improvements of shell-and-tube heat exchangers with helical baffles of different improved designs. Extensive results from experiments and numerical simulations indicated that these heat exchangers have better flow and heat transfer performance than the conventional baffled heat exchangers, therefore allowing to save energy, reduce cost, and prolong service life and operation time in industrial applications.…”

Comparative Study of Shell and Helically-Coiled Tube Heat Exchangers with Various Dimple Arrangements in Condensers for Odor Control in a Pyrolysis System

“…By condensing, the byproducts (such as the odors or dust) of the pyrolysis process are reduced and removed. The shell and tube heat exchanger (STHX) systems have played an important role to realize condensation [11], and it is important to increase the heat transfer performance for the best condensation conditions. Therefore, many researchers focus on the STHX systems, especially on the heat transfer performance.…”
