In this study we investigated double diffusional Catteneo-Christov heat flux model to understand mass and heat transfer of liquid mix Casson nanofluid discharged over a curved shrinking/stretching channel. To govern such flow, a evenly charged force is applied in the vertical direction to the flow stream. Intensities of thermal and concentration fluxes are monitored by involving relaxations in Fourier's law. In the midst of mathematical modelling of our envisaged flow problem, we established a structure of complex partial differential equations embedded with sundry parameters. Using variable conversion procedure in vogue, these equations are transformed into simpler version of order differential equations. Numerical simulation is completed through MATLAB solver bvp4c by setting the default tolerance. The solver is applied recursively to achieve the desired accuracy in picking the best blend of the assorted parameters we entrenched in the system. We noticed thermal and concentration relaxations caused the temperature and concentration profiles to reduce, but thermophoresis enhances both fluxes. Casson and magnetic indicator parameters are responsible for slowing down the speed of the flow in case of stretching channels, moreover, adding amounts of these parameters produced less skin friction. Stretching/Shrinking and curvature of the bent channel played significant roles in behavioral modifications of various profiles and are therefore useful for future course of action.

在这项研究中，我们研究了双扩散 Catteneo-Christov 热通量模型，以了解在弯曲的收缩/拉伸通道上排放的液体混合物 Casson 纳米流体的质量和热传递。为了控制这种流动，在垂直方向上向流动流施加均匀的力。通过涉及傅立叶定律中的弛豫来监测热通量和浓度通量的强度。在对我们设想的流动问题进行数学建模的过程中，我们建立了一个复杂的偏微分方程结构，其中嵌入了各种参数。使用流行的变量转换程序，这些方程被转换为阶微分方程的更简单版本。通过MATLAB求解器bvp4c通过设置默认容差完成数值模拟。求解器以递归方式应用，以在选择我们在系统中根深蒂固的各种参数的最佳组合时达到所需的精度。我们注意到热弛豫和浓度弛豫导致温度和浓度分布降低，但热泳增强了这两种通量。在拉伸通道的情况下，卡松和磁性指标参数负责减慢流动速度，此外，增加这些参数的数量会产生更少的皮肤摩擦。弯曲通道的拉伸/收缩和曲率在各种配置文件的行为修改中发挥了重要作用，因此对未来的行动方案很有用。我们注意到热弛豫和浓度弛豫导致温度和浓度分布降低，但热泳增强了这两种通量。在拉伸通道的情况下，卡松和磁性指标参数负责减慢流动速度，此外，增加这些参数的数量会产生更少的皮肤摩擦。弯曲通道的拉伸/收缩和曲率在各种配置文件的行为修改中发挥了重要作用，因此对未来的行动方案很有用。我们注意到热弛豫和浓度弛豫导致温度和浓度分布降低，但热泳增强了这两种通量。在拉伸通道的情况下，卡松和磁性指标参数负责减慢流动速度，此外，增加这些参数的数量会产生更少的皮肤摩擦。弯曲通道的拉伸/收缩和曲率在各种配置文件的行为修改中发挥了重要作用，因此对未来的行动方案很有用。
