The hybrid nanofluids are effectively working in terms of cooling where the temperature range is high and includes a broad range of thermal applications including electronic equipment cooling, heat exchangers, manufacturing industry, automotive industry, heat pipes and solar energy. Due to these facts, the current research focusses on the titanium oxide-iron oxide/ethylene glycol hybrid nanofluid motion over an exponentially stretching sheet. The influences such as radiation, electromagnetohydrodynamics (EMHD), viscous dissipation and Joule heating have also been considered into account. The flow model is converted and simplified to the system of ordinary differential equations by using similarity transformations and non-dimensional quantities. The resulting system is solved with the numerical procedure bvp4c Matlab technique. The outcomes of the present study are discussed through pictorial representations. It is concluded from the study that the stronger Grashof number declines the velocity profiles of titanium oxide/ethylene glycol nanofluid as well as titanium oxide (\(Ti{O}_{2}\))-iron oxide (\(F{e}_{2}{O}_{3}\))/ethylene glycol (\({C}_{2}{H}_{6}{O}_{2}\)) hybrid nanofluid. The thermal radiation enhances the temperature profiles of mono/hybrid nanofluids. The Nusselt number declines with the Eckert number.

EMHD 辐射氧化钛-氧化铁/乙二醇混合纳米流体流过指数拉伸片

混合纳米流体在高温范围内的冷却方面非常有效,包括广泛的热应用,包括电子设备冷却、热交换器、制造业、汽车工业、热管和太阳能。由于这些事实,目前的研究集中在氧化钛-氧化铁/乙二醇混合纳米流体在指数拉伸片上的运动。还考虑了辐射、电磁流体动力学 (EMHD)、粘性耗散和焦耳热等影响。利用相似变换和无量纲量将流动模型转化并简化为常微分方程组。生成的系统用数值程序 bvp4c Matlab 技术求解。本研究的结果通过图示进行了讨论。从研究中得出结论,更强的格拉肖夫数会降低二氧化钛/乙二醇纳米流体以及二氧化钛的速度分布(\(Ti{O}_{2}\) )-氧化铁( \(F{e}_{2}{O}_{3}\)) /乙二醇( \({C}_{2} {H}_{6}{O}_{2}\) ) 混合纳米流体。热辐射增强了单/混合纳米流体的温度分布。努塞尔数随埃克特数递减。
