This investigation provides a numerical simulation of mixed convection flow of magneto-Sutterby nanomaterial embedded in a Darcy–Forchheimer porous medium with the participation of Joule heating factor. Due to its numerous applications in biotechnology, thermal bioconvection involving swimming microbes and solar radiation impacts over an inclined stretching cylindrical surface with the convective heating and zero mass flux are chosen as suitable boundary conditions. The study utilizes the Sutterby fluid model to characterize the rheological behavior of the nano-polymeric suspension and incorporates the Darcy–Forchheimer (DF) model to account for the impedance of porous media in the transport equations. The governing nonlinear partial differential equations are converted as ordinary differential equations utilizing suitable similarity transformation and then treated numerically by employing approach Runge–Kutta–Fehlberg (RKF-45) and a shooting algorithm. Efficacy of numerous prominent factors on dimensionless velocity, temperature, concentration, friction factor, rate of heat transport, and motile density number is presented graphically and discussed in detail. The important outcomes of this study are: the resistance to flow is increased by a larger inertia coefficient because it causes the fluid particles to accelerate which diminishes the velocity profile. The study showed that enhancing the Brownian motion and radiation parameter enhanced the heat transfer rate at the surface.
