Global Computational Modeling of Cardiovascular Blood Flow
نویسنده
چکیده
The cardiovascular system is an internal flow network with multiple branches in which three-dimensional and pulsatile blood flow circulates. We propose a new paradigm of simulation-based biomedical engineering, which is designed as a useful means for predictive medicine. In order to achieve this paradigm a global computational modeling of cardiovascular blood flow is highlighted and some preliminary results are presented.

متن کاملPresentation of a Non-invasive Method of Estimating Arterial Stiffness by Modeling Blood Flow and Arterial Wall Based on the Determination of Elastic Module of Arterial Wall
Introduction: Arterial stiffness is an important predictor of cardiovascular risk. Several indices have been introduced to estimate the arterial stiffness based on the changes in the brachial blood pressure. Since the substitution of the blood pressure changes in the central arteries such as carotid with the blood pressure changes in the brachial results in error in the blood...
متن کاملComputational fluid dynamics study and GA modeling approach of the bend angle effect on thermal-hydraulic characteristics in zigzag channels
In the study, the thermal-hydraulic performance of the zigzag channels with circular cross-section was analyzed by Computational Fluid Dynamics (CFD). The standard K-Ꜫ turbulent scalable wall functions were used for modeling. The wall temperature was assumed constant 353 K and water was used as the working fluid. The zigzag serpentine channels with bend angles of 5 - 45° were studied for turbul...
