摘要

我们研究了菠萝叶纤维（PLF）和分散在水中的多壁碳纳米管（MWCNTs）纳米流体的传热传质特性。我们计算了不同条件下的Nusselt和Sherwood数以及表面摩擦系数。PLF是有机的，MWCNTs被广泛用于提高导热性。采用数值有限元方法求解方程，分析纳米颗粒对传递现象的影响。这两种纳米流体都能提高传输速率，MWCNTs表现出优异的热性能。PLF提供了可持续性和成本效益。这项研究有助于了解纳米流体、可持续材料和热管理中的应用。

Heat transfer analysis of a pineapple leaf fiber nanofluid/MWCNT–water convective flow over a disk

We examine the heat and mass transfer characteristics of nanofluid containing a pineapple leaf fiber (PLF) and multi-walled carbon nanotubes (MWCNTs) dispersed in water. We evaluate the Nusselt and Sherwood numbers and the skin friction coefficient under different conditions. The PLF is organic, MWCNTs are widely used for enhancing thermal conductivity. Equations are solved using numerical finite-element methods to analyze the impact of nanoparticles on transfer phenomena. Both nanofluids enhance transfer rates with MWCNTs showing superior thermal properties. The PLF offers sustainability and cost benefits. This study contributes to knowledge on nanofluids, sustainable materials, and applications in thermal management.
