More Information
Summary:The proposed model represents the construction of entropy generation, heat transport, and flow characteristics of Ag-TiO2/blood flow in a Darcy-Forchheimer stretching cylinder under the impact of Cattaneo-Christov heat flux and thermal radiation. The basic PDEs are converted into ODEs using correct similarity transformations. The 4th-order Runge-Kutta shooting system is used to solve these ODEs. Homotopy Perturbation Method (HPM) for the nonlinear system is developed for comparison purposes, and more accurate and reliable outcomes are illustrated through graphs and tables. The impacts of various factors on velocity, temperature, and entropy production are analyzed visually. The velocity profile is enhanced with larger magnetic field values, whereas the temperature profile yields inverse effect. Higher values of the Darcy-Forchheimer number enhance skin friction and heat transfer rates. In the present analysis, Ag-TiO2 are the nanoparticles in blood that are considered as the base fluid. This investigation has its own contribution to biomedical engineering, including medicine and electronics. The mentioned nanoparticles play an essential role in nanobiotechnology, particularly in cancer therapy and nanomedicine, because these metal nanoparticles are thought to improve the photocatalytic operation in the presence of titanium dioxide-drug delivery systems, particularly when drugs are injected into the bloodstream.
