Effect of Baffle on Pressure drop and Heat transfer in Shell and Tube Heat Exchangers

摘要：

Shell-and-tube heat exchangers in various sizes are widely used in industrial operations and energy conversion systems. Shell-and-tube heat exchangers have been very successfully designed according to Tubular Exchanger Manufacturers Association (TEMA) standards and using recommended correlation based analytical approaches. The shell side design of a shell-and-tube heat exchanger; in particular the baffle spacing, baffle cut and shell diameter dependencies of the heat transfer coefficient and the pressure drop are investigated by numerically modeling a small heat exchanger. The flow and temperature fields inside the shell and single tube pass heat exchanger with a variable number of baffles and turbulent flow. The numerical results show that, under the same mass flow rate M, the heat transfer rate Qs in shell side with 7 baffles is higher than others.
