Influence of thermal radiation and electromagnetic characteristics of micropolar ternary hybrid nanofluid flow over a slender surface

The increasing demand for sustainable energy has significantly boosted the requirements for efficient solar-thermal power systems. In this context, ternary nanofluids have the potential to greatly enhance the efficiency of solar-thermal systems by significantly improving heat transport capabilities. This work systematically and extensively analyzes the energy transition to enhance mechanisms of heat transport in renewable energy systems using ternary nanofluid flow comprising iron (III) oxide, gold, and titanium dioxide nanoparticles suspended in polymer. The combined effect of non-Fourier heat flux, multiple slips, and electro-magnetohydrodynamic on slender surfaces is also considered in the flow problem. An appropriate technique is employed to normalize and simplify the governing flow equations into a nonlinear ordinary differential equations system. The Galerkin weighted residual technique is employed to solve the modeled equations through the MATHEMATICA 11.3 software. The findings indicate that increasing radiation and porosity parameters increases fluid temperature. Furthermore, the impact of the exterior concave and inner convex surfaces intensifies, while the electric field effect raises the fluid temperature profile. An increase in the porosity parameter also enhances the micro-rotation profile.
