The present paper is concerned to study the influence of second-order slip, mixed convection, viscous and Joule dissipations, thermophoretic and Brownian diffusions on steady stagnation point nanofluid flow over a stretching sheet embedded in a porous medium with passive control of nanoparticles. Graphs for velocity, temperature and concentration of present nanofluid flow model, obtained by using spectral relaxation method, are discussed in detail for various parameters. Apart from it, present results are verified by previously available results as well as regression analysis is performed for the local Nusselt number for making this model more effective in industries and engineering. From the statistical analysis of local Nusselt number, it is suggested that small variation in thermophoretic parameter leads to large perturbation in local Nusselt number in comparison to Brownian motion parameter, and the presence of Eckert number leads to strengthen Brownian and thermophoretic diffusions.

二次多元回归模型和谱弛豫方法分析具有二阶滑移的驻点纳米流体流动

本论文涉及研究二阶滑移、混合对流、粘性和焦耳耗散、热泳和布朗扩散对纳米流体在嵌入多孔介质中的拉伸片上稳定​​驻点流动的影响，并通过纳米粒子的被动控制。对于各种参数，详细讨论了通过使用谱弛豫方法获得的当前纳米流体流动模型的速度、温度和浓度图。除此之外，目前的结果也得到了先前可用结果的验证，并对当地的 Nusselt 数进行了回归分析，以使该模型在工业和工程中更有效。从局部努塞尔数的统计分析，
