Thermal and Fluid Flow Analysis of Shell-and-Tube Heat Exchangers with Smooth and Dimpled Tubes

This current work mainly focuses on the enhancement of heat transfer and fluid flow characteristics shell-and-tube exchangers by incorporating dimples smooth or conventional tubes. With aid ANSYS (Fluent) commercial software package, Computational Fluid Dynamics (CFD) simulations under a steady-state condition were conducted exchanger having single shell 12 tubes (with without dimples), 50% baffle cut, 100mm spacing turbulent flow. The temperature, velocity, pressure fields at tube zone in both cases are analyzed. computational dynamics results with dimpled compared (smooth) However, show that has higher overall coefficient than is an Open Access article distributed terms Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, reproduction any medium provided original properly cited.
