Polymer solutions high viscous fluids and they are very sensitive to temperature gradients due to this reason controlling temperature is key research problem in polymerization reactors, mixers and coating system. Rotating parallel plate reactors used in viscous resins to maintain uniform heating and cooling effects during solvent removal and polymerization. This current study provides detailed mathematical analysis on improving heat transfer in rotating system and also preserving uniform temperature in the system. Hybrid nanofluid is prepared with copper and graphene oxide with base fluid as water. Mathematical model is developed by boundary layer approximation equations for momentum, temperature and similarity solution is obtained using MATLAB software. Casson rheological model is utilised to analyse non-Newtonian behaviour of hybrid nanofluid. Energy equation is embedded with thermal radiation and exponential heat source sink terms. Momentum, temperature profiles are visualised with respect to distinct fluid parameters and analysed. Friction co-efficient at the boundaries and rate of heat transfer is computed and tabulated. It is observed that radial velocity profile is suppressed for rotation parameter. Nusselt number increases with rise of volume fraction. Casson parameter increases velocity profile.
