In this work, shear stress distributions on three-dimensional realistic health and dissected aortic vessels are simulated by the Computational Fluid Dynamics (CFD) Technique. A health aorta model demonstrates that the maximum wall stress distribution is p In this work, shear stress distributions on three-dimensional realistic health and dissected aortic vessels are simulated by the Computational Fluid Dynamics (CFD) Technique.
