摘要

本文计算了含铜(Cu)和钴铁氧体(CoFe2O4)纳米颗粒(NPs)的混合纳米流体在挤压板上的流动特性。在生物医学领域,在极少数情况下流体通过静态通道流动。同样,在工业现场,我们也经常观察到流体流过组成板而不是固定板(汽车发动机中喷嘴和活塞之间的流动)。CoFe2O4和Cu纳米颗粒由于其广泛的应用,在医学和技术研究中受到了极大的关注。为此,将这些现象以pde体系的形式表示,并附加了吸力/注入效应、热源效应、化学反应效应和磁场效应。通过相似替换,将偏微分方程系统简化为偏微分方程的无量纲集。进一步讨论了参数延拓法的计算方法。为了验证所得结果的有效性和准确性,与已有的研究结果进行了验证。结果通过图显示和评估。实验结果表明,混合纳米流体的速度和能量传输能力与纳米流体有关。能量分布受非定常挤压项的影响而减小,受吸力系数、吸热产热和下板拉伸片的影响而增大。

Computational Simulation of Unsteady Squeezing Hybrid Nanofluid Flow Through a Horizontal Channel Comprised of Metallic Nanoparticles
The characteristics of hybrid nanofluid flow contained copper (Cu) and cobalt ferrite (CoFe2O4) nanoparticles (NPs) across a squeezing plate have been computationally evaluated in the present report. In biomedical fields, in very rare cases fluid flow through a static channel. Similarly in industrial sights, we are also often observed that the fluid flows through comprising plates rather than fixed plates (flow in vehicle’s engine between nozzles and piston). CoFe2O4 and Cu nanoparticles are receiving huge attention in medical and technical research due to their broad range of applications. For this purpose, the phenomena have been expressed in the form of the system of PDEs with the additional effect of suction/injection, heat source, chemical reaction, and magnetic field. The system of PDEs is simplified to the dimensionless set of ODEs through similarity replacements. Which further deals with the computational approach parametric continuation method. For the validity and accuracy of the outcomes, the results are confirmed with the existing works. The results are displayed and evaluated through Figures. It is detected that the hybrid nanoliquid has a greater ability for the velocity and energy conveyance rate as related to the nanofluid. Furthermore, the energy profile declines with the consequences of unsteady squeezing term, while enhances with the effects of suction factor, heat absorption and generation, and lower plate stretching sheet.
