Maintaining a continuous thermal convective power supply is very essential in many industries and thermal systems, this is because it helps in improving the efficiency of engineering machines and engines. Thus, hybridized electromagnetic nanoparticle in a heat supporting non-Newtonian fluid is a good platform to enhance thermal power energy. Based on its usefulness, this study focuses on the hybridization of zirconium dioxide (ZrO2) and copper (Cu) tangent hyperbolic nanofluid in ethylene-glycol(EG) (C2H6O2) solvent for thermal power optimization. With quadratic Boussinesq approximation, the fluid is influenced by electromagnetic induction and thermal convection. Via similarity quantities, an invariant derivative model is obtained. The model is completely solved using weighted residual method coupled with partition and one-third Simpson’s quadrature technique. The presented outputs revealed that entropy generation is minimized and thermodynamic equilibrium is achieved with rising values of the electric and magnetic field terms. Heat propagation is augmented with an enhanced electric field loading and nanoparticle volume fraction for hybrid nanofluid than unitary nanofluid. Also, current density is build-up for rising Williamson and thermal convection terms.
