Abstract This study examines hybrid nanofluids flow on an extendable surface using thermophoresis, Brownian motion, micropolar and magnetic effects. To control the thermal diffusions, the effects of Joule heating have also incorporated in energy equations. The concentration diffusion is controlled through use of Arrhenius energy term in concentration equation. Moreover, multiple slip effects have used at the physical boundaries of the flow system. The governing equations were converted to dimensionless form and subsequently solved by bvp4c method. The studied parameter used in this work along with their ranges are 0.1 ≤ M ≤ 1.4, 0.3 ≤ K ≤ 0.9, 0.1 ≤ α ≤ 0.9, 0.3 ≤ n ≤ 0.9, 0.10 ≤ Q ≤ 0.25, 0.1 ≤ Nt ≤ 0.4, 0.1 ≤ Nb ≤ 0.4, 0.1 ≤ Ec ≤ 0.4, 0.1 ≤ β ≤ 0.7, 0.1 ≤ Kr ≤ 0.4, 0.1 ≤ E ≤ 0.4 and 1.0 ≤ Sc ≤ 4.0. As conclusion of the work it has found that with progression in magnetic influence the linear velocity declines while the skin friction has augmented. Progression in micropolar factor causes augmentation in linear velocity while the micro-rotational velocity declines in this phenomenon. Thermal profiles have amplified with intensification in heat source factor, thermophoresis factor, Brownian motion factor, magnetic factor and Eckert number while declines with intensification in thermal slip factor. The profiles of concentration have amplified with augmentation in thermophoresis factor and activation energy factor while reduced with growth in chemical reaction factor and concentration slip factor. The current results have been validated through comparison with established works.
