Surface flow characteristics of blood-based gold–silver Casson hybrid nanofluid with thermal relaxation: Python-based simulation for enhanced drug delivery applications

Purpose The design of advanced drug delivery mechanisms is crucial to the efficient and controlled delivery of therapeutic agents. In this context, the utility and thermal properties of nanoparticles are essential under various conditions. The current study aims to examine the flow of heat and fluid in a blood-based Casson hybrid nanofluid as it flows over a flat surface within a porous material. This study also examines how energy is lost due to the magnetic force and the effects of heat radiation and heat relaxation, which are explained using the Cattaneo–Christov (C–C) heat flux model. Design/methodology/approach The nanofluid comprises both gold and silver nanoparticles, effectively enhancing the thermal conductivity and drug delivery efficiency. The mathematical model designed to represent the proposed phenomena is converted into a standard nondimensional model for the utility of similarity rules and then solved numerically using standard built-in function in the Python programming tool for the boundary value problem. Findings The authors obtain the computation by using the Python programming tool, which allows us to choose the appropriate factors. The comparative results presented numerically validate the present outcomes with those from earlier studies in a particular case. Originality/value Comprehensive study integrating blood-based gold and silver nanoparticles and thermal relaxation effects. Modeling of an expandable surface packed with a porous matrix enhanced drug delivery activities. The utility of the Python programming tool for the solution of the transformed model.
