CFD Analysis on Effect of Angulation in A Healthy Abdominal Aorta-Renal Artery Junction

The recent developments in computational fluid dynamics (CFD) can be useful observing the detailed haemodynamics renal artery bifurcation for clinical evaluation and treatment. present study focuses on haemodynamic behaviour of blood as it flows through abdominal aorta-renal junction an idealistic healthy with varying angles to aorta, i.e. from 30° 90° increments 15°. This is examine effect angulation determine whether arterial geometry plays a role prediction atherosclerotic lesions. three-dimensional models used this were generated using ANSYS WORKBENCH 19.0, numerical simulation was done FLUENT 19.0 solver. flow assumed Newtonian, incompressible laminar. Haemodynamic parameters such velocity, wall pressure shear stress along variation are compared among different models. As increased, velocity at ostial region decreased by 14% 52% respectively. Wall same saw increase 3%. Therefore, arteries higher bifurcating aorta observed more prone formation precursor future studies stenosis.
