Abstract

The paper investigates the role of complete velocity slip on the axisymmetric peristaltic transport of Ellis fluid through a uniform flexible tube considering the long wavelength and tiny Reynolds number assumptions. The equations governing the axisymmetric flow are solved and provided the analytical expressions for axial velocity, stream function, pressure difference for shear thickening and shear thinning fluids and the effect of emerging parameters on the pressure rise with time averaged flux and stream line patterns have been discussed graphically. The trapping phenomenon results showed that the size of trapping bolus enhances with increasing values of first and second slip parameters.

Ellis流体通过柔性管的蠕动泵送，具有完全的滑移效应

考虑长波长和小雷诺数假设，研究了完全速度滑移对Ellis流体通过均匀柔性管轴对称蠕动输运的影响。对轴对称流动方程进行了求解，给出了剪切增稠和剪切稀化流体的轴向速度、流函数、压差的解析表达式，并图解地讨论了新出现的参数对压力随时间平均通量和流线模式的影响。捕获现象的结果表明，随着第一和第二滑移参数的增大，捕获量的大小增大。

期刊介绍： TJPRC: Journal of Naval Architecture and Marine Engineering (JNAME) is a peer reviewed journal and it provides a forum for engineers and scientists from a wide range of disciplines to present and discuss various phenomena in the utilization and preservation of ocean environment. Without being limited by the traditional categorization, it is encouraged to present advanced technology development and scientific research, as long as they are aimed for more and better human engagement with ocean environment. Topics include, but not limited to: marine hydrodynamics; structural mechanics; marine propulsion system; design methodology & practice; production technology; system dynamics & control; marine equipment technology; materials science; under-water acoustics; satellite observations; and information technology related to ship and marine systems; ocean energy systems; marine environmental engineering; maritime safety engineering; polar & arctic engineering; coastal & port engineering; aqua-cultural engineering; sub-sea engineering; and specialized water-craft engineering. International Journal of Naval Architecture and Ocean Engineering is published quarterly by the Society of Naval Architects of Korea. In addition to original, full-length, refereed papers, review articles by leading authorities and articulated technical discussions of highly technical interest are also published.
