Abstract The underlying intention of the present work is to elaborate boundary layer flow Carreau fluid over a non‐linear stretching curved surface. Firstly, we derived equation motion for two‐dimensional surface using constitutive relation. Employing well‐known approximations theory (order magnitude analysis), terms higher and next order have been neglected. We developed an appropriate similarity transformation that reduced considered partial differential into ordinary (self‐similar formulation). MATLAB built‐in function usually known as bvp5c utilized get numerical solution problem. impact power‐law index ( n ), Weissenberg number curvature parameter k ) on velocity profile skin friction are analyzed through several graphs tables. obtained results also verified by employing shooting method Maple software. reveal both thickness increase enlarging dimensionless

The purpose of this paper is to provide a novel reference for the early diagnosis and treatment atherosclerosis. Two-dimensional governing equations fractional-order Maxwell fluid flow in local stenotic artery are established, taking real physiological pulsating blood at inlet into consideration. Drawing support from finite difference method as well L1 formula, vorticity stream functions introduced acquire numerical solutions velocity, function, pressure. distribution narrowed arteries within pulse cycle discussed. Furthermore, influences degree stenosis δ, length parameter L0, fractional order α, relaxation time λ on crucial medical indicators, including average wall shear stress, oscillatory index, relative residence time, pressure revealed. results show that deceleration reversal phases pulsatile critically affect progression arterial stenosis, increasing α weakens development while has opposite effect. This study expected serve formulating standards key indicators vascular stenosis.
