Computational Analysis of Cardiovascular Hemodynamics
The human body requires a complex circulatory system to supply nutrients to, and to remove metabolic waste products from, its tissues. Given this primary purpose, circulatory function is closely related to the hemodynamic characteristics of blood vessels. This includes not only macroscale fluid dynamics, but also mass transfer in the microvasculature. Many experimental and clinical studies have...
متن کاملLagrangian analysis of hemodynamics data from FSI simulation.
We present the computation of lagrangian-based flow characterization measures for time-dependent, deformable-wall, finite-element blood flow simulations. Applicability of the algorithm is demonstrated in a fluid-structure interaction simulation of blood flow through a total cavopulmonary connection (Fontan procedure), and results are compared with a rigid-vessel simulation. Specifically, we rep...
متن کاملComputational Hemodynamics of Abdominal Aortic Aneurysms
An existing computational model is extended to simulate Newtonian and non-Newtonian blood flow in three dimensional idealized abdominal aortic aneurysm (AAA) geometries in order to calculate the wall shear stress (WSS) and wall shear stress gradient (WSSG) along the arterial wall and obtain the velocity profile. From these, the locations of high and low WSS and WSSG can be determined, as well a...
متن کاملQuery-driven Multiscale Data Postprocessing in Computational Fluid Dynamics
Massively parallel computational fluid dynamics codes that have to stream solution data to a visualisation or postprocessing component in each time step often are IO-bounded. This is especially cumbersome if the succeeding components require the simulation data only in a coarse resolution or only in specific subregions. We suggest to replace the streaming data approach found in many application...
متن کاملComputational hemodynamics of portal vein hypertension in hepatic cirrhosis patients.
Portal vein hypertension generally occurs in liver diseases like hepatic cirrhosis. It causes hemodynamic changes that are closely related to liver disease. At advanced stages of hepatic cirrhosis, portal vein hypertension leads to the atrophy of the right lobe of the liver and the hypertrophy of the left lobe through a process that has not yet been fully explained. Based on the hemodynamic cha...
