In this paper, we discussed the effect of activation energy on mixed convective heat and mass transfer of Williamson nanofluid with heat generation or absorption over a stretching cylinder. Dimensionless ordinary differential equations are obtained from the modeled PDEs by using appropriate transformations. Numerical results of the skin friction coefficient, Nusselt number, and Sherwood number for different parameters are computed. The effects of the physical parameter on temperature, velocity, and concentration have been discussed in detail. From the result, it is found that the dimensionless velocity decreases whereas temperature and concentration increase when the porous parameter is enhanced. The present result has been compared with published paper and found good agreement.

活化能作用下MHD Williamson纳米流体在拉伸圆柱体上的研究

在本文中，我们讨论了活化能对威廉姆森纳米流体混合对流传热和传质的影响，以及在拉伸圆柱体上产生或吸收的热量。通过使用适当的变换，从建模的PDE获得无量纲的常微分方程。计算了不同参数下的皮肤摩擦系数，努塞尔数和舍伍德数的数值结果。已经详细讨论了物理参数对温度，速度和浓度的影响。从结果可以发现，当提高多孔参数时，无因次速度降低，而温度和浓度升高。目前的结果已与已发表的论文进行了比较，并取得了很好的一致性。
