In this study, the experimental analysis was performed on the shell-and-tube type heat exchanger containing segmental baffles at different orientations. In the current work, three angular orientations (θ) 0°, 30°, and 60° of the baffles were analyzed for laminar flow having the Reynolds number range 303–1516. It was observed that, with increase of Reynolds number from 303 to 1516, there was a 94.8% increase in Nusselt number and 282.9% increase in pressure drop. Due to increase of Reynolds number from 303 to 1516, there is a decrease in nondimensional temperature factor for cold water (ω) by 57.7% and hot water (ξ) by 57.1%, respectively.

Shell And Tube

This study aims to analyze and develop a heat exchanger (HE) application for the manufacture of silica nanoparticles synthesis from agricultural waste. This shell and tube-type HE is designed simply, but it still refers to the existing design rules. The design of a shell and tube type HE with one pass shell and tube with turbulence flow. The specifications of the HE apparatus are 1.93 m in shell length, 0.203 m in shell diameter, 0.020 m in inner tube diameter, 0.022 m in outer tube diameter, and 0.016 m in thickness. The results showed an effectiveness value of 66.38% with an impurity factor of 0.01314. This informed that although the shell and tube-typed HE does not meet the requirements and standards for being set in industrial applications, it can be useful as a learning method regarding the design process, working mechanism, and analyzing the performance of the HE.
