Zusammenfassung:In industrial process, improving the transfer of heat has become the primary focus. In comparison with convectional heat transfer fluids and nanofluids containing single nanoparticles, hybrid nanofluids have the potential to offer improved heat transfer performance and thermophysical features. In order to approximate the flow and thermal transport properties, a numerical investigation is conducted in this study. The present study investigates the radiative hybrid silica–alumina/ethylene glycol nanofluid flow properties of heat transfer and fluid flow toward thin needle. The fluid flow model is designed to be governed by a partial differential equation. The PDEs are turned into ODEs using similarity requirements, and then solved numerically using the finite difference approach via the built-in MATLAB function bvp4c. The outcome of flow controlling parameters on velocity, temperature, friction drag, and heat transport rate is presented. The study exhibits that duality of solutions occurs in a particular range when χ c < χ ≤ - 2.2 and unique solution at χ > - 2.2 . The results revel that reduction in skin friction and heat transport rate occurs by the inclusion of magnetic strength in hybrid nanofluid. It is also found that when the size of solid nanoparticle increased, the rate of heat transfer across the needle’s surface dramatically improved.
