High-Fidelity Simulations for Improved Cardiovascular Disease Diagnosis and Device Design
Abstract
Simulations are a powerful tool to uncover the physics of engineering and biomedical flows. Understanding the flow physics is a prerequisite to improve the design of biomedical devices, relate form to function of organs, or relate disease to hemodynamics. Nevertheless, such applications typically involve complex shapes, moving boundaries, fluid-structure interactions, pulsatile flows, and a wide range of scales, which is quite challenging even to the most advanced numerical techniques. We have overcome many of these challenges using our computational framework, parallelized to efficiently utilize high-performance computing clusters, which handles moving bodies using a sharp-interface immersed boundary method, and solves the flow equations and the immersed bodies in a fully implicit manner using a Newton-Krylov method with an analytical Jacobian. A few examples in which high-fidelity simulations have led to discoveries for new parameters for diagnosis/prognosis of a disease such as aneurysms or improving biomedical devices such as heart valves will be presented. At the end, the future developments for advancing knowledge will be discussed.
