Boundary layer flow and heat transfer enhancement by utilizing Casson ternary nanofluid past a horizontal cylinder in a non-Darcy porous medium with thermal radiation effects – Non-similar solutions

Abstract

The aim of this study is to examine the results of MHD, radiation and Casson ternary fluid over a horizontal cylinder with a saturated porous medium. The nanofluids used in this study are trihybrid, consisting of Cu, Al₂O₃ and Tio₂ particles suspended in blood as the base fluid. The dimensional form of governing equations is transformed into dimensionless form by manipulating non-similar solutions. The conservation equations are solved using the Keller Box Method (KBM). The presence of several emerging dimensionless parameters, namely the Casson fluid parameter (β), Darcy number (Da), Forchheimer parameter (∧), radiation parameter (Rd) and magnetic field (M) on fluid momentum and energy changes in the boundary layer regime are investigated in detail. The Prandtl value (Pr) for blood is determined to be 21. The application of porous medium models spans across various fields, including engineering, environmental science, biology, and materials science.
