This paper deals with the study of the effect of a variable normal electric field on Jeffry flow through a heating vibrating cylindrical tube with moving endoscope. Under the assumption of long wavelength and the use of appropriate non-dimensional quantities, the analytical solutions for axial and radial velocities, stream function, fluid pressure, electrical potential function and temperature distribution are obtained. The results show that the volume of the trapped bolus increases by the increase of amplitude ratio, endoscope radius, Jeffry parameter and electrical Rayleigh number, whereas it has an opposite effect on the increase in the endoscope velocity and temperature parameter. Furthermore, it is observed that the effects of the amplitude ratio and Jeffry parameter on the axial velocity in the presence of electric field are greater and clearer than those in the absence of electric field.

带有移动内窥镜的杰弗里流体通过加热振动圆柱管的电动流体流动

本文研究了可变正电场对带移动内窥镜的加热振动圆柱管的杰弗里流的影响。在长波长和使用适当的无量纲量的假设下,获得了轴向和径向速度,流函数,流体压力,电势函数和温度分布的解析解。结果表明,随着振幅比,内窥镜半径,Jeffry参数和电瑞利数的增加,捕获的弹药的体积增加,而对内窥镜速度和温度参数的增加却产生相反的影响。此外,
