Blood flow rate monitoring is of great interest to engineers in biomedical sciences and medical investigators, because it may be used to identify a number of cardiovascular conditions, including arrhythmia and atherosclerosis. Many researchers have studied cardiac and arterial blood flow using many non-Newtonian fluid models. Blood-like properties are found in several non-Newtonian fluid models, including the tangent hyperbolic, Casson, Williamson, Oldroyd B, Powell–Eyring fluid, etc. The shear-thinning qualities of the tangent hyperbolic fluid model allow it to depict the rheological aspects of blood more adequately. This work aims to provide a comprehensive description of the effects of gyrotactic microorganisms on the wedge and stagnation point of a plate, along with the flow of tangent hyperbolic nanofluid over it. A set of appropriate self-similarity variables is used to transform the fluid transport equations into ordinary differential equations. The Runge–Kutta–Fehlberg procedure is then rummage-sale to solve these equations. The fluid’s transport qualities are demonstrated through the use of graphs and tables, which illustrate the impact of active parameters. Microorganisms with high motile density are typically associated with Weissenberg numbers. The thermophoresis parameter decreases in wedge and stagnation point flow examples, while it increases in plate flow cases. The multiple linear regression analysis reveals that the parameter of temperature difference significantly influences the heat transfer rate. The study sheds light on a number of topics, including hyperthermia therapies (such as those used to combat cancer), and the transmission of heat and mass in blood streams inside the cardiovascular system.
