### INFLUENCES OF RADIATIVE HEAT TRANSFER ON HYDROMAGNETIC HYBRID NANOFLUID FLOW THROUGH TWO ROTATING SURFACES

**ABSTRACT**

This study explores the growth of heat transfer rate for hybrid nanofluid-flow through two rotary plates fixed parallel. For improvement of thermal conductivity nanoparticles of Cu and graphene oxide have dispersed in water. The fluid-flow has been influenced by thermal radiation. Magnetic effects with strength, B0, has employed in the normal direction the plates. The set of equations that controlled the fluid-flow system have been shifted to dimension-free form employing suitable variables. The resultant set of equations has been solved by HAM. It has revealed in this work that with upsurge in the values of magnetic and rotational factors the linear velocity retarded while micro-rotational velocity upsurge. Intensification in volumetric fractions of nanoparticles results in retardation of fluid motion in all directions and growth in thermal flow profiles. Thermal flow profiles are also supported by the augmenting values of radiation factor. It has further revealed that hybrid nanofluid has a better flow performance in contrast of traditional nanofluid.
