The flow of fluid over a spinning disk has a broad scope of numerous applications. It is employed in various things, including medical equipment, the braking system of cars, gas turbines, plastic films, and glass production. As a result of these applications, we considered the phenomena of Darcy Forchheimer's three-dimensional flow on nanoparticles suspended in based CMC-water fluid. The influence of thermal radiation and convective conditions is studied. Moreover, the Buongiorno model is utilized to compute the Brownian motion and the thermophoretic effect. To generate the non-dimensionalized governing equations, suitable alterations are put into use. These equations are then utilized with Matlab BVP4c. Graphs are used to analyze the behavior of velocity distributions, and thermal and concentration profiles at different parameter values. In addition, the solutions to the flow problem have been analyzed in terms of several other physical variables on velocity, temperature, concentration, drag force, heat, and mass transfer. According to the findings, it is clear that an escalates in the value of the rotation parameter leads to an increase in the radial velocity and axial velocity. In contrast, an opposite pattern is followed in the Forchheimer number. Finally, some engineering quantities are evaluated numerically and presented in tabular forms.
旋转圆盘上的流体流动在众多应用领域有着广泛的范围。它被应用于各种事物,包括医疗设备、汽车制动系统、燃气轮机、塑料薄膜和玻璃生产。由于这些应用,我们考虑了基于羧甲基纤维素钠(CMC) - 水流体中悬浮纳米颗粒上的达西 - 福希海默三维流动现象。研究了热辐射和对流条件的影响。此外,利用布翁焦尔诺模型来计算布朗运动和热泳效应。为了生成无量纲控制方程,采用了适当的变换。然后将这些方程与Matlab的BVP4c一起使用。通过图表分析不同参数值下速度分布、温度和浓度分布的行为。此外,还根据速度、温度、浓度、阻力、热传递和质量传递等其他几个物理变量对流动问题的解进行了分析。根据研究结果,很明显旋转参数值的增加会导致径向速度和轴向速度增加。相反,福希海默数呈现相反的模式。最后,对一些工程量进行了数值评估并以表格形式呈现。
