Using magnetohydrodynamics (MHD), the thermal energy and mass transport boundary
layer flow parameters of Reiner–Philippoff fluid (non-Newtonian) are numerically investigated. In
terms of energy and mass transfer, non-linear radiation, Cattaneo–Christov double diffusions, convective conditions at the surface, and the species reaction pertaining to activation energy are all
addressed. The stated governing system of partial differential equations (PDEs) is drained into a
non-linear differential system using appropriate similarity variables. Numerical solutions are found
for the flow equations that have been determined. Two-dimensional charts are employed to demonstrate the flow field, temperature and species distributions, and rate of heat and mass transfers for
the concerned parameters for both Newtonian and Reiner–Philippoff fluid examples. The stream
line phenomenon is also mentioned in this paper. A table has also been utilized to illustrate the
comparison with published results, which shows that the current numerical data are in good accord.
The findings point to a new role for heat and mass transfer. According to the findings, increasing
values of solutal and thermal relaxation time parameters diminish the associated mass and thermal
energy layers. The current study has significant ramifications for chemical engineering systems.
