The flow of nanofluid over a variable thickened stretching sheet is studied in this article. Non-Fourier's heat flux and non-Fick's mass flux are incorporated for heat and mass flow analysis. Silver (Ag) and Copper (Cu) are considered nanoparticles with water as base fluid. The resulting equations are transformed into the dimensionless form using similarity transformation and solved by RK-4 with the shooting method. The impact of the governing parameters on the dimensionless velocity, temperature, concentration, skin friction coefficient, streamlines, and finally isotherms are incorporated. It is observed that increment in power-law index parameter uplifts the fluid flow, heat, and mass transfer. The increase in the magnitude of skin friction coefficient in (x-direction) with wall thickness parameter is high for nanofluid containing silver nanoparticles as compared to copper nanoparticles.
本文研究了变厚度拉伸平板上的纳米流体流动。为了进行热流和质量流分析，考虑了非傅里叶热通量和非菲克质量通量。银（Ag）和铜（Cu）被认为是纳米粒子，水是基液。使用相似变换将所得方程转换为无量纲形式，并使用 RK-4 方法与打靶法求解。研究了控制参数对无量纲速度、温度、浓度、摩擦系数、流线和等焓线的影响。结果表明，幂律指数参数的增加会提高流体流动、传热和传质。与铜纳米粒子相比，含银纳米粒子的纳米流体的壁面厚度参数对（x 方向）摩擦系数的影响更大。
