Abstract

Tangent hyperbolic fluids characterized by shear-thinning behavior, are widely utilized in diverse industrial and scientific fields such as polymer engineering, inkjet printing, biofluids modeling, thermal insulation materials, and chemical manufacturing. Additionally, double-diffusive convection involving simultaneous heat and mass transfer driven by temperature and concentration gradients plays a critical role in many natural and industrial systems, including oceanic circulation, geothermal energy extraction, crystal solidification, alloy formation, and enhanced oil recovery. The current work examines the peristaltic transport of a tangent hyperbolic nanofluid under the concurrent effects of thermal radiation, electroosmotic forces, slip boundary conditions, and double diffusion. The governing nonlinear equations are numerically solved using Mathematica’s NDSolve command after being simplified under the presumptions of a long wavelength, a low Reynolds number, and Debye-Huckel linearization. The analysis reveals that a rise in the velocity slip parameter decreases the core fluid velocity but increases it closer to channel walls, while increased solutal Grashof number and electroosmotic parameter result in non-uniform velocity distributions, reducing the flow towards the left wall and increasing it towards the right. The pressure gradient increases with higher electroosmotic effects and Helmholtz-Smoluchowski velocity, but decreases under more intense thermal radiation and increased Prandtl number. The magnetic field increases pressure in the retrograde area and moves the enhanced zone towards the right wall, emphasizing increased flow resistance. Also, the trapping effects intensify with increasing solutal Grashof number and Helmholtz-Smoluchowski velocity, providing better particle transport and mixing in microfluidic devices.
