“…The dispersion of nanomaterials gives rise to Brownian motion ( Nb ) and thermophoresis ( Nt ). It is very clear that the presence of nanomaterials facilitates the heating of the liquid and thus temperatures are enhanced as pointed out by Buongiorno 31 that the Nb and Nt contribute to the enhancement of thermal conductivity of the fluid, which is reflected in higher temperatures. At

η = 2.0

, when

italicNr = 0.1

θ_{w} = 1.5

the temperature is enhanced by 18.5% more than that of the pure base liquid.…”

This research communication explores the impact of wall slips along with the suspension of nanomaterials in a chemically reactive micropolar liquid stream on a stretched surface with convective heating. Activation of energy is analyzed through the modified Arrhenius function. Radiative heat flux with nonlinearity and temperature‐dependent thermal source (sink) are considered in the heat transmission process. The Cattaneo–Christov approach featuring the time of thermal relaxation is employed. Successive application of scaling analysis followed by the Runge–Kutta–Fehlberg numerical approach delivered computational solutions for the partial differential equations delineating the problem under study. The response of flow variables for different values of various emerged physical variables is elaborated in detail via graphical and numerical presentations. Comparison of the outcome of the current analysis for certain cases is in accordance with the outcomes available in the literature. The findings reveal that pairs of velocity, microrotation, temperature, and species concentration oppositely reacted to both parameters of slip. The temperature of the nanofluid is improved by 18.5%, for specified values of radiation and temperature ratio parameters over that of the pure base liquid. Activation energy augments concentration. The drag coefficient declines with growing thermal and solutal Grashof numbers. Sherwood number is enhanced for higher values of the temperature difference and chemical reaction parameters.
