The current model represents the construction of entropy generation, heat transport and flow characteristics of /blood flow in a Darcy-Forchheimer stretching cylinder under the impact of Cattaneo-Christov heat flux and thermal radiation. The basic PDEs are turned into ODEs by using the 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 the comparison purpose and more accurate and reliable outcomes is illustrated through graphs and tables. The effects of various factors on velocity, temperature, and entropy production are analysed visually. The velocity profile improves with larger magnetic field values, whereas the temperature profile has the reverse effect. Higher values of the Darcy-Forchheimer number enhance skin friction and heat transfer rates. In the present analysis, are nanoparticles blood is considered as base fluid. This investigation is helpful in biomedical engineering, including medicine and electronics. They play an essential role in nano biotechnology, particularly in cancer therapy and nano medicine, because these metal nanoparticles are thought to improve photo catalytic operation in the presence of titanium dioxide-drug delivery systems, particularly when drugs are injected into the blood stream.
