Sensitivity analysis on steady bionanofluid boundary layer flow

Bionanofluid is a water-based fluid consisting both nanoparticles and living motile microorganisms. Improving nanofluid instability, inducing mixing, enhancing heat and mass transfer are the benefits of adding living motile microorganisms to a nanofluid. Hence, the continuous investigation of the...
