Analytical and numerical investigation of thermal distribution for hybrid nanofluid through an oblique artery with mild stenosis

Abstract In this study, the accuracy of three methods to simulate thermal diffusivity profile in oblique stenosis artery with hybrid nanofluid and influence volume fraction heat sources nanofluid, including Al 2 O 3 Cu, is studied. Comparing analytical for reliable answers important new studies. Also, source parameter S temperature evolution Akbari–Ganji Method (AGM), Finite Element (FEM), Runge–Kutta method are studied calculate artery's profile. The results compared by reference value, AGM more accurate than FEM less 7 percent error, 9 error. maximum difference between happened near wall vessel. 0.02, 0.03, 0.05 chosen studying.
