Thermo‑Diffusion and Diffusion‑Thermo Effects on MHD Third‑Grade Nanofluid Flow Driven by Peristaltic Transport

摘要

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.
