Cattaneo-christov heat flux theory in tangent hyperbolic hybrid nano fluids with thermal radiation for renewable energy applications

The aim of current paper is to explore the dynamics of Tangent hyperbolic hybrid nano fluid flow and heat transfer over a stretchy surface, combined effect of thermal radiation and Cattaneo-Christov heat flux effects also incorporated in the energy equation. Hybrid nano fluids are advanced class of nano fluid have several engineering applications due to their enhanced thermal, electrical, and rheological properties. Here we developed a mathematical model for two-dimensional hybrid nano fluid containing particles copper (Cu) and alumina oxide (Al₂O₃) suspended with base fluid H₂O. Variable viscosity and viscous dissipation aspect also amalgamated in the present study. After applying the dimensionless variables, the governing PDEs are converted into ODEs. The numerical computations are performed with the help of MATLAB software. The most important outcomes predefined pertinent parameters like magnetic parameter, Weissenberg number, relaxation time, thermal radiation parameter, prosperity parameter, convective parameter, Prandtl number, heat source parameter, Eckert number, on velocity and temperature profile are thoroughly examined graphically and physically. There occur increment in the temperature profile of hybrid nano fluid than regular nano fluid. Also over current outcomes shows close agreement for a particular cases
