In this paper, a generalized Newtonian nanofluid in a bio-microfluidics channel due to combined effects of peristalsis and external applied electric field in the presence of thermal radiation and Joule heating is considered. The Poisson and Nernst-Planck equations are taken into account. The obtained non-linear coupled ordinary differential equations are simulated numerically. The impacts of several parameters under the applied electric field on velocity, temperature, concentration, trapping isothermal lines, Nusselt, and Sherwood numbers are presented graphically. It is observed that the number of isothermal lines increases with the electro-osmotic parameter thermophoresis parameter and Brownian motion parameter while perter out with thermal radiation. The results are helpful to design the micro pumps/chips used in medical engineering and improved the thermal efficiency and the durability of microchip cooling devices.

在本文中，考虑了由于存在热辐射和焦耳热的情况下蠕动和外部施加电场的综合作用，生物微流体通道中的广义牛顿纳米流体。考虑了Poisson和Nernst-Planck方程。对获得的非线性耦合常微分方程进行数值模拟。以图形方式显示了在电场作用下几个参数对速度，温度，浓度，等温线俘获线，Nusselt和Sherwood数的影响。可以看出，等温线的数量随着电渗参数热泳参数和布朗运动参数的增加而增加，而随着热辐射的扩散而增加。
