简介：在这篇文章，我们在影响温度依赖者粘性下面作为基础液体与水向一张拉长的表讨论碳nanotubes的二维的停滞点流动。类似转变被用来为nanofluid简化管理边界层方程。这是在有可变粘性的一张拉长的表上的CNT的停滞点流动上的第一篇文章。粘性的一个众所周知的雷纳兹模型被使用。单个墙CNT与水被用作基础液体。结果有相关边界条件的非线性的联合方程用射击数字地被解决方法。无尺寸的速度，温度，皮肤磨擦，和Nusselt数字上的流动参数的影响被探索并且介绍处于良好的竟技状态图并且身体上解释了。

简介：这份报纸学习正切的成层的magnetohydrodynamic(MHD)流动经过使倾向的指数地拉长的表面的夸张nanofluid。流动受到速度，热，并且solutal边界条件。部分微分系统用适当转变被归结为平常的微分系统。减少的系统为会聚的系列答案被解决。速度，温度，和集中地为不同物理参数被讨论。温度和热边界层厚度为Brownian运动和thermophoresis效果的大价值显著地增加的结果indi-佳肴。快活参数加强速度领域，这也被观察，显示出温度和nanoparticle卷部分侧面的减少的行为。
