Evaluation of Performance Correlations and Simulation of Single-phase Shell and Tube Heat Exchangers Equipped with Kenics Static Mixers

Abstract:
Shell and tube heat exchangers are widely used in industries. These heat exchangers have their own limitations and special working conditions. They have always been designer’s first choice because of their advantages such as available design standards and ability to handle a wide range of heat duties. Design engineers have made a lot of effort to increase the performance of shell and tube heat exchangers. The installation of static mixers is one of the most effective ways to enhance heat transfer in the tube side of heat exchangers. In this study، by the evaluation and modification of performance correlations given for static mixers، the more reliable ones have been identified. In addition، using CFD، velocity، temperature، and pressure profiles for both laminar and turbulent regimes have been studied. For a typical case study، the heat transfer and flow pattern of water flow inside a tube equipped with six helical Kenics inserts have finally been analyzed.
