Nanofluids based on CNTs/ethylene glycol have a potential role in contributing to industrial applications like heat exchangers, domestic refrigerator, electronics cooling, etc. The aim and novelty of the present research is to communicate the significance of the Coriolis force and Darcy-Forchheimer stretched flow of ethylene glycol (EG) conveying carbon nanotubes (CNTs) in a rotating frame. Furthermore, entropy analysis is the main focus in this study. Two types of CNTs known as multiwalled (MWCNT) and single-walled (SWCNT) carbon nanotubes are considered. Ethylene glycol (EG) is treated as the base liquid. Xue’s model is utilized for the physical aspects of specific heat, density and thermal conductivity. The heat transfer mechanism is modeled through nonlinear thermal radiation, viscous dissipation and convective condition. The governing flow problems have been computed numerically via the NDSolve method. Outcomes for single-walled and multi-walled CNTs are arranged and compared. Our findings reveal that entropy generation is accompanied by an increasing trend in the Brinkman number and temperature ratio parameter. Temperature increases with the intensification of radiative and convective variables. Moreover, the temperature gradient has marginally larger values in the case of SWCNT, when compared with MWCNT.

基于 CNT/乙二醇的纳米流体在促进工业应用（如热交换器、家用冰箱、电子冷却等）方面具有潜在作用。本研究的目的和新颖之处在于传达科里奥利力和 Darcy-Forchheimer 拉伸的重要性乙二醇 (EG) 在旋转框架中输送碳纳米管 (CNT) 的流动。此外，熵分析是本研究的主要重点。考虑了称为多壁（MWCNT）和单壁（SWCNT）碳纳米管的两种类型的CNT。乙二醇 (EG) 被视为基液。Xue 的模型用于比热、密度和热导率的物理方面。传热机制通过非线性热辐射、粘性耗散和对流条件建模。控制流问题已通过 NDSolve 方法进行数值计算。排列和比较了单壁和多壁 CNT 的结果。我们的研究结果表明，熵的产生伴随着布林克曼数和温度比参数的增加趋势。温度随着辐射和对流变量的增强而升高。此外，与 MWCNT 相比，SWCNT 的温度梯度值略大。
