研究了热传导和感应磁场,对Johnson-Segalman流体蠕动流的影响.目的是研究感应磁场对非Newton流体蠕动流的影响.在长波和低Reynolds数假设下,被简化为一组二维的Johnson-Segalman流体的流动方程.采用常规的摄动方法,求得流函数、磁力函数和轴向压力梯度的解.对不同的参数,绘出了压力增量、温度、感应磁场、压力梯度和流函数表达式的简图并给出解释.
The influence of heat transfer and induced magnetic field on peristaltic flow of a Johnson-Segalman fluid was studied. The purpose of the present investigation was to study the effects of induced magnetic field on the peristaltic flow of non-Newtonian fluid. The two-dimensional equations of Johnson-Segalman fluid were simplified by assuming a long wave length and low Reynolds number. The obtained equations were solved for the stream function,magnetic force function,and axial pressure gradient by using a regular perturbation method. The expressions for the pressure rise,temperature,induced magnetic field,pressure gradient,and stream function were sketched for various embedded parameters and were interpreted.
