Abstract

This study examines MWCNTs-PG nanofluid with a uniform dispersion of MWCNTs in PG. It is assumed that both MWCNTs and PG exist thermally in equilibrium and no slip occurs between them. MWCNTs were suspended in PG uniformly and played a significant role. Firstly, the problem is formulated by utilizing empirical correlations, thermophysical attributes, and similarity equations. Then the model is treated numerically along with the coupling of a shooting algorithm. The results against the pertinent flow quantities were plotted and provide a basis for a comprehensive discussion, investigating whether MWCNTs-PG has high thermal storage characteristics under the effects of thermal radiation and combined convection effects. Due to their high energy storage capability, these fluids are reliable for industrial applications.

摘要

本研究考察了多壁碳纳米管均匀分散在丙二醇中的多壁碳纳米管-丙二醇纳米流体。假定多壁碳纳米管和丙二醇在热方面处于平衡状态,且它们之间不发生滑移。多壁碳纳米管均匀悬浮在丙二醇中并发挥了重要作用。首先,利用经验关联式、热物理性质和相似方程来阐述该问题。然后,结合打靶算法对模型进行数值处理。绘制了与相关流量有关的结果,为全面讨论提供了依据,研究了在热辐射和混合对流效应影响下多壁碳纳米管-丙二醇是否具有高蓄热特性。由于这些流体具有高储能能力,它们在工业应用中是可靠的。
