Abstract

Abstract The present numerical study is aimed at investigating the effect of rotation on heat transfer to non-Newtonian nanofluid flowing through a pipe. Non-Newtonian fluid flow under laminar condition with heat transfer finds the applications in various industries like food processing, pharmaceutical and polymer etc. Various proportions (1–3%) of copper nanoparticles are mixed with water to study the heat transfer rates non-Newtonian nanofluid flowing through the rotating pipe. Effect of rotation rate on heat transfer rates are also studied. In this study for 1% nanofluid at a constant rotation rate of 0.8, the Nusselt number is increased by 119.45%. The highest thermal performance factor (TPF) is 1.74, observed at N = 0.8, Pe = 5000, and for 1% volume concentration of non-Newtonian nanofluid.

管道旋转对流过管道的层流非牛顿纳米流体传热的影响:CFD分析

摘要本数值研究旨在探讨旋转对非牛顿纳米流体在管道中传热的影响。层流条件下的非牛顿流体传热在食品加工、制药、聚合物等行业得到了广泛的应用。将不同比例(1-3%)的铜纳米颗粒与水混合，研究非牛顿纳米流体流经旋转管道的换热率。研究了旋转速率对传热速率的影响。在本研究中，对于1%的纳米流体，在恒定的0.8旋转速率下，努塞尔数增加了119.45%。当N = 0.8, Pe = 5000，非牛顿纳米流体体积浓度为1%时，热性能因子(TPF)最高，为1.74。

期刊介绍： Chemical Product and Process Modeling (CPPM) is a quarterly journal that publishes theoretical and applied research on product and process design modeling, simulation and optimization. Thanks to its international editorial board, the journal assembles the best papers from around the world on to cover the gap between product and process. The journal brings together chemical and process engineering researchers, practitioners, and software developers in a new forum for the international modeling and simulation community. Topics: equation oriented and modular simulation optimization technology for process and materials design, new modeling techniques shortcut modeling and design approaches performance of commercial and in-house simulation and optimization tools challenges faced in industrial product and process simulation and optimization computational fluid dynamics environmental process, food and pharmaceutical modeling topics drawn from the substantial areas of overlap between modeling and mathematics applied to chemical products and processes.
