Mixed convective flow of blood biofluids containing magnetite ferroparticles past a vertical flat plate: shapes-based analysis

The blood circulatory system, which is made up of an opaque network of blood vessels, is responsible for transporting important nutrients and oxygen to the body's active tissues as well as removing waste materials. The transmission of ions, cells, gases, and macromolecules between both the blood and tissue is handled by this system. Blood flow dynamics have an important role in the onset and development of cardiovascular illnesses. Here, in this article, the authors have presented the magnetohydrodynamic flow of magnetite blood-based nanofluid which plays a significant role in cancer therapeutics. Furthermore, by producing higher temperatures around tumors, these types of nanoparticles play an intriguing function in the killing of malignant cells while causing no harm to nearby strong cells. The mixture of blood and ferroparticles are analyzed past a vertical flat plate. Additionally, the ferroparticles have considered in three different shapes which include platelet, cylinder, and brick. The stagnation point flow along with mixed convection phenomena has been taken into account. The presence of non-Newtonian nanofluid flow has been considered incompressible and laminar. Suitable similarity transformations are considered to transform the system of partial differential equations into ordinary differential equations. The transformed system has been solved analytically and then compared with numerical technique, and have found a great agreement between both techniques. The results showed that the presence of hemoglobin molecules in red blood cells that are magnetic in nature, it concludes that blood is the magnetic fluid which can be controlled by applying a suitable magnetic field during surgeries. The greater magnetic parameter has thickened the thermal boundary layer of the blood based ferroparticles. Thus, an augmenting impression is found for assisting flow, while a reducing impact is found for opposing flow. Additionally, the greatest impact of magnetic parameter is found for platelet-shaped ferroparticles. The augmented mixed convection parameter speeds up the buoyancy forces which have accelerated the fluid motion, while retarded the thermal profile.
