Viscoplastic Hybrid Nanofluids Flow Through Vertical Stenosed Artery

The present study examines the viscoplastic hybrid nanofluids flow driven by the pumping due to a stenosed artery through the vertical cylindrical tube. Hall and ion-slip currents’ effects and magnetic field effects on the flow characteristics, thermal characteristics, and concentration profiles are analyzed. Hybrid nanofluids are considered blood-based Cu/Al 2 O 3 (copper-aluminum oxide) where blood is considered viscoplastic nature and Casson model is employed to study the viscoelasticity of the blood. An appropriate mathematical formulation has been made based on the basic principles of the fluid dynamics, and mass, momentum, energy, concentration equations are considered. To determine the temperature, concentration, and velocity profiles, a well-known perturbation method is used. Using Mathematica’s built-in DSolve function instruction, the expressions for stream function, wall shear stress, Nusselt number, Sherwood number, and blood flow resistance impedance are computed. A comparative analysis of present result with existing results has also been made to validate the model and methodology. Basic standard results for the velocity, temperature, and concentration under the effects of nondimensional parameters and numbers have been analyzed and discussed in detail. Moreover, the alterations in trapping phenomena, resistance impedance, wall shear stress, Nusselt number, and Sherwood number with respect to other parameters have been recorded. The results of the present model may be applicable in various health care issues particularly in circulatory system where the blood is flowing through stenosed arteries and drug deliver through this system.
