A numerical study of tiny particles experiencing thermal and reaction migration in a micropolar fluid over a stretching sheet with Newtonian heating

Abstract

ABSTRACT Substantial research on a micropolar fluid is currently being done. These novel materials offer various applications in bionic engineering and prosthetic design. The influences of cross-diffusive (diffusion-thermo and thermo-diffusion) on the stream of micropolar fluid via permeable stretching sheet under Newtonian heating are investigated in this study. The assumed mathematical model is then transformed using appropriate similarity transformations into its non-dimensional system. The resulting ordinary derivative formulation is solved through the spectral Chebyshev scheme with collocating integration. Graphically, the impacts of all critical factors on dimensionless velocity, microrotation, thermal distribution, and mass transfer are investigated. Tables are created to depict the interaction of various factors on engineering quantities. The outputs are compared with the accessible literature to demonstrate the effectiveness of the spectral Chebyshev schema, and excellent agreement is obtained.
