A numerical simulation of a two-dimensional Eyring-Powell nanofluid flow is carried out through a Riga plate with radiative walls. Simultaneous contributions of chemical reaction and activation energy have also been taken into account on the mixed convection flow. Lubrication effects are applied by considering second order slip boundary condition in order to reduce the role of skin friction. A set of highly nonlinear and coupled differential equations are tackled with the help of “Pseudo-spectral collocation method” by developing numerical code on MATLAB. A detailed parametric study is performed that reveals that more energy adds to the system in response to slip parameter and Brownian motion of the nano-particles. Numerical results have also been compiled and tabulated. This is worth noticing that skin friction coefficient reduces due to modified Hartmann factor while heat flux is an increasing function of Prandtl number. However, there is a prominent increase in mass flux against all parameter, except activation energy.

二维Eyring-Powell纳米流体流通过带有辐射壁的Riga板进行了数值模拟。在混合对流中也考虑了化学反应和活化能的同时贡献。通过考虑二阶滑移边界条件来施加润滑作用，以减少皮肤摩擦的作用。借助“伪谱配点法”解决了一组高度非线性和耦合的微分方程通过在MATLAB上开发数字代码。进行了详细的参数研究，结果表明，响应滑移参数和纳米粒子的布朗运动，系统中增加了更多的能量。数值结果也已汇总并制成表格。值得注意的是，由于修正的哈特曼因数，皮肤摩擦系数降低，而热通量是普朗特数的增加函数。但是，除活化能外，针对所有参数的质量通量都有显着增加。
