Bio-convective and chemically reactive hybrid nanofluid flow upon a thin stirring needle with viscous dissipation

Abstract In this work, the thermal analysis for bio-convective hybrid nanofluid flowing upon a thin horizontally moving needle is carried out. The chemical reaction and viscous dissipation has also considered for flow system in the presence of microorganism. The hybrid nanoparticles comprising of Co...
