| Abstract: | This paper investigated the flow and heat transfer characteristics for shell-and-tube heat exchangers with continuous helical baffles and segmental baffles. The resistance factor and heat transfer correla-tions for shell-side regions have been obtained. The comparison among heat transfer exchangers with continuous helical baffles, segmental baffles and non-continuous helical baffles has been made, and it is found that the heat exchangers with continuous helical baffles is superior to the heat exchangers with segmental baffles and non-continuous helical baffles when the shell-side velocity increased. |
