Two-dimensional mixed convection radiative nanofluid flow along with the non-Darcy permeable medium across a wavy inclined surface are observed in the present analysis. The transformation of the plane surface from the wavy irregular surface is executed via coordinate alteration. The fluid flow has been evaluated under the outcomes of heat source, thermal radiation, and chemical reaction rate. The nonlinear system of partial differential equations is simplified into a class of dimensionless set of ordinary differential equations (ODEs) through a similarity framework, where the obtained set of ODEs are further determined by employing the computational technique parametric continuation method (PCM) via MATLAB software. The comparative assessment of the current outcomes with the earlier existing literature studies confirmed that the present findings are quite reliable, and the PCM technique is satisfactory. The effect of appropriate dimensionless flow constraints is studied versus energy, mass, and velocity profiles and listed in the form of tables and figures. It is perceived that the inclination angle and wavy surface assist to improve the flow velocity by lowering the concentration and temperature. The velocity profile enhances with the variation of the inclination angle of the wavy surface, non-Darcian term, and wavy surface term. Furthermore, the rising value of Brownian motion and thermophoresis effect diminishes the heat-transfer rate.
在本分析中，观察到二维混合对流辐射纳米流体流动以及非达西渗透介质穿过波浪形倾斜表面的情况。通过坐标变换将平面从波浪形不规则表面进行转换。在热源、热辐射和化学反应速率的影响下对流体流动进行了评估。通过相似框架将非线性偏微分方程组简化为一类无量纲常微分方程组（ODEs），其中通过MATLAB软件使用计算技术参数连续法（PCM）进一步求解得到的常微分方程组。将当前结果与早期现有文献研究进行的对比评估证实了本研究结果相当可靠，并且PCM技术令人满意。研究了适当的无量纲流动约束对能量、质量和速度分布的影响，并以表格和图表的形式列出。可以看出，倾斜角和波浪形表面通过降低浓度和温度有助于提高流速。速度分布随着波浪形表面倾斜角、非达西项和波浪形表面项的变化而增强。此外，布朗运动和热泳效应的上升值会降低传热速率。
