The current paper examines the thermo-diffusion and diffusion-thermo effects on MHD third-grade nanofluid driven by peristalsis. The governing equations are linearized by adopting the low Reynolds number and long wavelength approximations. The Adomian series expression for velocity, stream function, pressure, concentration and temperature are acquired. The effect of sundry variables are discussed and illustrated graphically. The results reveal that the temperature values are enhanced with increasing Dufour number and the Soret number diminishes the concentration. Further, it is found that this study can be used for fabrication of semiconductor devices, manipulation of DNA and separation of biomolecules, etc.

蠕动运输对MHD纳米级纳米流体流动的热扩散和热扩散效应

本文研究了蠕动驱动的MHD三级纳米流体的热扩散和扩散热效应。通过采用低雷诺数和长波长近似将控制方程线性化。获得了速度，流函数，压力，浓度和温度的Adomian级数表达式。讨论并以图形方式说明了各种变量的影响。结果表明，温度值随Dufour数的增加而增加，而Soret数则降低了浓度。此外，发现该研究可用于半导体器件的制造，DNA的操纵和生物分子的分离等。
