Effect of Viscous Dissipation and Heat Source on Flow and Heat Transfer of a Dusty Fluid Over an Unsteady Stretching Sheet

  • 摘要: 研究含尘流体在不稳定伸展面上,作水动力学边界层流动及其热交换问题.研究中计及摩擦生热(粘性耗散)和内部发热或吸热的影响.应用适当的相似变换,将控制流动和热交换的基本方程组,变成一组非线性的常微分方程.利用Runge-Kutta-Fehlberg-45格式对变换后的方程进行数值求解.按发热进程分两种不同情况分析:VWT(变壁面温度)和VHF(变热通量).物理参数,如像磁场参数、流(体)-固(体微粒)的相互作用参数、不稳定参数、Prandtl数、Eckert数、含尘微粒的数量密度以及热源/汇参数,分别绘出这些物理参数变化时的速度和温度分布曲线;同时,列表和讨论了对壁面温度梯度函数和壁面温度函数的影响.
