Abstract Oblique stagnation point flow of incompressible Maxwell nanofluid past a stretching cylinder with active and passive controlled nanoparticles concentration condition is discussed numerically. The suitable coordinate decomposition reduce the governing boundary layer equations into the system of nonlinear ordinary differential equations which are approximated by Keller box procedure for several values of pertinent parameters. The Numerical results are compared and validated with existing ones as particular cases and found to be an excellent agreement. Velocity profile and lines of flow are sketched to discuss the Obliqueness of the flow. The temperature and concentration profiles drawn to illustrate the influence of involved parameters also variations in local Nusselt and Sherwood numbers are presented through tabular data. It is observed that the behavior of tangential velocity for the viscoelastic fluid and concentration of nanoparticles against thermophoresis diffusion over the cylinder are quite opposite when compared with the results over flat sheet. The temperature distribution and concentration of nanoparticles decreases with elasticity of the fluid.

麦克斯韦纳米材料在拉伸圆柱体上的非正交驻点流动

摘要 数值讨论了不可压缩麦克斯韦纳米流体在主动和被动控制纳米粒子浓度条件下通过拉伸圆柱体的斜驻点流动。适当的坐标分解将控制边界层方程简化为非线性常微分方程组，该方程组通过 Keller box 程序对相关参数的几个值进行近似。将数值结果与现有的数值结果作为特定案例进行比较和验证，发现是一个很好的一致性。绘制速度剖面和流动线以讨论流动的倾斜度。为说明相关参数的影响而绘制的温度和浓度曲线，以及当地 Nusselt 和 Sherwood 数的变化通过表格数据呈现。观察到，与平板上的结果相比，粘弹性流体的切向速度和纳米颗粒浓度对圆柱上热泳扩散的行为完全相反。纳米粒子的温度分布和浓度随着流体的弹性而降低。
