Abstract: This study investigates the mixed convection heat transfercharacteristics of micropolar nanofluid containing motile microorganismsas it is passing over a stretching sheet. The governing equations of thefluid flow and boundary conditions are solved via similarity analysisusing the fourth-order Runge–Kutta method. To verify the accuracy andvalidity of the method, the results are compared with those of severalprevious studies. The results are presented in terms of distribution ofthe velocity, particle micro-rotation, temperature, nanoparticleconcentration, and density of motile microorganisms over the stretchingsheet. The skin friction, coupled stress, mass transfer rate, and therate of microorganism transfer away from the sheet are also examined. Itcan be concluded that the Nusselt number, coupled stress, frictioncoefficient, and Sherwood number are independent of the bioconvectionLewis number Lb. On the other hand, the rate of motilemicroorganism transfer away from the sheet to the fluid increases withLb.
