Abstract

Cancer is the most deadly and dangerous of mainly its patients. The current research has suggested that the nanoparticle containing gold can treat and trounce it since these materials have a lofty atomic quantity that produces the temperature and guides to the handling of malignant tumors. The enthusiasm of current research deals with the steady 2D flow with heat diffusion of blood which transmits the micropolar nanoliquid with gold particles through a curved shrinking/stretched surface. The impact of radiation is also invoked. The coordinates in the curvilinear form are utilized to formulate the mathematical model of flow equations. The similarity technique is employed to transmute the leading PDEs into nonlinear ODEs. The altered nonlinear ODEs are solved through a bvp4c based on a 3-stage Lobatto technique. The numerical outcomes for the heat transport rate and the skin factor along with the micro-rotation, temperature, and velocity fields are presented via plots. The dual natures of solutions are observed for precise values of stretched/shrinking parameter. The physical enlightenments of the sketches are presented to distinguish the phenomena of blood flow by heat transfer in distinct conditions. The results suggest that the blood velocity increases due to suction in the first solution, and decreases in the second solution, while the micro-rotation upsurges and temperature declines in both solutions. Also, the nanofluid temperature uplifts due to the radiation in both solutions.
