Abstract: Two‐dimensional, laminar, steady‐state MHD (magnetohydrodynamic) Darcy‐Forchheimer MWCNT‐MoS2/micropolar water‐base hybridized nanofluid flowing over shrinking/stretching sheet is considered. The thermal radiation, heat sink/source influences have also been taken into account. Ordinary differential equations (ODEs) system is achieved by the implication of similarity transformations on PDEs (partial differential equations). The resulting equations are numerically solved by the implication of shooting scheme through Maple software. The double solutions are generated at multiple ranges of applied parameters. Therefore, stability analysis of the outcomes has been made and first‐branch solution is stable, while second‐branch is unstable. The influence of volume fractions of nanoparticles and specified flow parameters are determined on the couple stress, skin friction, Sherwood and Nusselt numbers. An increment in volume‐fraction of nanoparticle increases the Sherwood number and decreases Nusselt number. The increase in nanoparticle's volume fractions increases velocity profile. The velocity reduces due to an augmentation in micro‐material, Darcy‐Forchheimer and suction parameters. The increasing Biot number, nanoparticle's volume‐fractions and radiation increase the temperature profiles. An increment in chemical reaction, suction and Schmidt number cause to a decrement in concentration profiles. [ABSTRACT FROM AUTHOR]
