Abstract

Present investigation based on the axisymmetric squeezing flow of various alloy nanofluids between parallel disks embedding with porous medium. To enhance the heat transfer properties we have considered two special type of alloy nanoparticles such as AA7072 which contains 98% of Aluminum (Al), 1% of Zink (Zn), rest Silica (Si), Iron (Fe), Copper (Cu), and AA7075 contains 90% of Al, 5%–6% of Zn, 3% of manganese (Mg), 1%–2% of Cu with additive Si, Fe, and Mn. The effects of velocity slip and temperature jump boundary conditions are also considered. Suitable similarity transformation along with Maxwell model physical properties for nanofluid are use to formulate the dimensionless governing ordinary differential equations. Physical significance of characterizing parameters are presented graphically and discussed. The numerical computations for engineering coefficients are shown in tabular form. In a comparative study, the current result shows a good correlation with the earlier established result that confirms the convergence of the solution methodology. Further, the major outcomes are laid down as: The velocity is more prominent for AA7075-water nanofluid in the first region for applied magnetic field whereas reverse impact is observed in the second region. The fluid temperature retards when there is a rise in thermal slip parameter. The shear rate of AA7072-water based nanofluid is higher than other nanofluid AA7075.
时间相关的AA7072和AA7075水基纳米流体在速度和热滑移条件下通过平行圆盘的挤压流动分析
本文研究了不同合金纳米流体在嵌入多孔介质的平行圆盘间的轴对称挤压流动。为了提高传热性能,我们考虑了两种特殊类型的合金纳米颗粒,如AA7072,它含有98%的铝(Al), 1%的锌(Zn),其余的二氧化硅(Si),铁(Fe),铜(Cu), AA7075含有90%的铝,5%-6%的锌,3%的锰(Mg), 1% - 2%的铜,并添加Si, Fe和Mn。同时考虑了速度滑移和温度跳变边界条件的影响。利用适当的相似变换,结合纳米流体的麦克斯韦模型物理性质,建立了无量纲控制常微分方程。对表征参数的物理意义进行了图解和讨论。工程系数的数值计算以表格形式给出。在比较研究中,目前的结果与先前建立的结果具有良好的相关性,证实了求解方法的收敛性。主要结果为:在外加磁场作用下,aa7075 -水纳米流体在第一个区域的速度更显著,而在第二个区域则相反。当热滑移参数升高时,流体温度减慢。水基纳米流体aa7072的剪切速率高于其他纳米流体AA7075。
