Magnetized Cross tetra hybrid nanofluid passed a stenosed artery with nonuniform heat source (sink) and thermal radiation: Novel tetra hybrid Tiwari and Das nanofluid model.

• Cross non-Newtonian tetra hybridity bio-nanofluid flowing along stenosed artery with convective heat transport is analyzed. • Impacts like heat source/sink, viscous dissipation, Joules heating as well as nonlinear thermal radiation are probed. • Numerical treatment with the utilization of MATLAB builtin bvp4c scheme is introduced. • Temperature within the arteries is intensified by the advantage of a thermal radiation and viscous dissipation. Researchers around the planet are attempted to explore the influence of various non-Newtonian fluids with the mono and dihybrid nanoparticles in the status of blood flowing arteries to investigate the heat transference aspect for the cure of various diseases. Current examination is created to investigate the effect of extended novel tetra hybrid Tiwari and Das nanofluid model on blood flow arteries with consideration of Cross non-Newtonian fluid model. Heat transference assessment has been taken with the insertion of impacts like heat source/sink, viscous dissipation, Joules heating as well as nonlinear thermal radiation. PDE are designed to investigate the momentum of blood flowing and temperature analysis. The governing PDE are converted into ODE with the application of similarity conversions and furthermore managed these ODE numerically with the utilization of MATLAB builtin bvp4c scheme. The obtained outcomes are studied numerically as well as graphically in the case of diverse dimensionless variables ranges between 0.5 ≤ M ≤ 2 , 0.1 ≤ W e ≤ 4 , 0.1 ≤ n ≤ 1.5 , 0.1 ≤ γ ≤ 2 , 0.5 ≤ R d ≤ 2 , 19 ≤ P r ≤ 22 , 0.1 ≤ θ w ≤ 1.5 , 0.1 ≤ E c ≤ 2.1 , 0.5 ≤ U ≤ 2 , 0.5 ≤ W ≤ 2 versus velocity, temperature, wall frictional factor and heat transition rate. From obtained outcomes it is reflected that the surface drag phenomenon weakens by the boost of a Weissenberg number and an increment variation in magneto force provides a resistance against the fluid flow. Temperature within the arteries intensifies by the advantage of a thermal radiation and viscous dissipation. [ABSTRACT FROM AUTHOR]
