| 摘 要： | 研究Jeffrey流体流过有限长管道时的蠕动流.在外加磁场作用时,流体呈导电性.分析是在长波长和低Reynolds数近似假设下完成.得到了压力梯度、体积流量、平均体积流量和局部壁面剪应力的表达式.研究了松弛时间、延迟时间和Hartman数,对压力、局部壁面剪应力以及蠕动泵机械效率的影响.还研究了回流现象,调查了沿管道壁波数非整倍数时的传播情况,研究有限长管道传播的内在特性. |
| 关 键 词： | 蠕动流 磁流体动力学 Jeffrey流 有限长管道 机械效率 回流 |

| Abstract: | The peristaltic flow of Jeffrey fluid through a tube of finite length was studied.The fluid was electrically conducting in the presence of an applied magnetic field.Analysis was carried out under the assumption of long wavelength and low Reynolds number approximations.Expressions of pressure gradient,volume flow rate,average volume flow rate and local wall shear stress were obtained.The effects of relaxation time,retardation time and Hartman number on pressure,local wall shear stress and mechanical efficien... |
