Abstract
Aortic aneurysms have become one of the most common life-threatening aortic diseases diagnosed with severe consequences, including aortic dissection. A three-dimensional computational fluid dynamics (CFD) model is developed to simulate the nonlinear behaviour of an aorta with aortic aneurysms for the prediction of wall shear stress as one of the leading causes for dissection. The CFD simulations are built using biomechanical system parameters of pulsatile blood flow, non-Newtonian model for blood, aneurysm size and shape. Incorporating these factors in the model and numerical simulations model is critical to ensure the reliability as well as a real and accuracy of the results. Influences in rupture predictions due to these parameters are discussed, and the generated model can numerically predict weak regions of the aorta with low wall strength or experiencing higher stress, which identifies the higher risks for ruptures. The biomechanical model introduced in this chapter could be utilised to estimate the connection between aortic aneurysms and the risk of aortic rupture.
