摘要
研究内窥镜中Walter B流体的蠕动流,在圆柱坐标系中建立问题的模型,目的是研究内窥镜对Walter B流体蠕动流的影响.以delta为摄动参数,使用正规的摄动法求出解析解.利用数值积分,求得压力增量和摩擦力的近似解析解.用图形给出了Walter B流体所显现参数的影响.
The peristaltic flow of a Walter' s B fluid in an endoscope was studied. The problem was model in cylindrical coordinates system. The main theme of the present analysis was to study the endoscopic effects on the peristaltic flow of Walter' s B fluid, because to the best of authors' knowledge no investigation had been made up to yet in peristaltic literature to study the Walter' s B fluid in an endoscope. The analytical solutions were carried out using regular perturbation method by taking delta as erturbation parameter. The approximate analytical solu tions for pressure rise and friction forces were evaluated using numerical integration. The effects of emerging parameters of Walter' s B fluid were presented graphically.
