Mixed convection of nanofluid at the lower stagnation point of a horizontal circular cylinder: Brinkman–viscoelastic
Researchers have formulated the Brinkman–viscoelastic model to study the convective heat transfer of viscoelastic fluids traversing porous media recently. Nevertheless, they did not employ nanofluids. Currently, scientists and researchers are employing nanofluids and hybrid nanofluids in their studies, products, and technologies due to their ability to enhance the transfer of heat. Therefore, the aim of this research is to study the heat transfer of a viscoelastic fluid with nanoparticles as it moves over a horizontal circular cylinder in a saturated porous region at
