摘要

In the constantly evolving realm of blood-based fluid dynamics, meticulous management of thermal and fluidic properties within living organisms is crucial for advancing diagnostic and therapeutic applications. This study focuses on the complex interactions within a Casson hybrid nanofluid comprising ferrosoferric oxide (Fe3O₄) and molybdenum disulfide (MoS₂) nanostructures dispersed in blood plasma. The research explores the influence of thermal diffusion, diffusion-thermo, and non-linear (quadratic) thermal radiation on the fluid’s transportation dynamics, while taking into account sophisticated boundary conditions such as the Smoluchowski temperature jump and the Maxwell velocity slip. These boundary conditions closely replicate physiological environments at the micro/nanoscale. The governing PDEs that describe the flow of the nanomaterial are transmuted and parametrized through a similarity transformation. These resulting equations are simulated by utilizing the finite difference method to ensure numerical stability and accuracy. The results suggest that both variants of nanomaterials substantially improve thermal conductivity and energy transfer, with temperature and velocity distributions being influenced by temperature jump and velocity slip conditions. Moreover, thermal diffusion and diffusion-thermo processes result in a decrease in temperature and an increase in velocity and concentration. This study presents an advanced physics-driven framework for the development of biomedical devices and fluid-based therapeutic systems.
