Thermal and mass transfer in peristaltic flow of Jeffrey nanofluid with double diffusive convection and ohmic heating

The study of nanofluid mechanics with heat transfer has received particular attention from researchers and engineers due to the extensive range of nanofluid applications in various sectors and advancements in nanotechnology. It is a far more fascinating part of the study of fluid dynamics. Driven by its practical uses in the rheological modeling of numerous significant liquids, this study employs the Jeffrey nanofluid model for its applications in cooling systems, drug delivery, energy systems and microfluidics. This study examines the combined influence of tilted magnetic field, double-diffusive convection, Ohmic heating, thermal radiation, Hall current and heat generation on the peristaltic motion of Jeffrey nanofluid through a symmetric porous conduit. Utilizing a lubrication approach and appropriate dimensionless parameters transforms the dimensional governing equations into nondimensional simplified forms. By using the homotopy perturbation approach, nonlinear PDE solutions are calculated analytically. An analysis of various key parameters has been conducted using the derived analytical expressions for velocity, temperature, concentration, nanoparticle fraction, pressure rise and streamlines, providing valuable insights into the complex physical phenomena within this diverse field. It is noticed that the enhancement in the Darcy parameter and nanoparticle Grashof number improves the velocity profile in the center of the conduit. The temperature profile escalates with the augmentation of the Brinkman number, Brownian motion, thermophoresis and heat source variables. Furthermore, a 1.34% increase in the skin friction coefficient is noticed when we increase the nanoparticle Grashof number from 0.1 to 0.5. Similarly, a 1.19% decrement is found in the skin friction coefficient for increasing the magnetic parameter from 0.2 to 0.6. The results of this study are validated for some special cases. Further, it is noticed that the findings of this study agree quite well with the previous studies in the literature.
