Book Synopsis Numerical Simulation of Blood Flow in Arterial Stenosis Under Steady and Pulsatile Flow Conditions by : Parth Pranavbhai Dave
Download or read book Numerical Simulation of Blood Flow in Arterial Stenosis Under Steady and Pulsatile Flow Conditions written by Parth Pranavbhai Dave and published by . This book was released on 2011 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cardiovascular diseases (CVDs) are among the leading causes of death in the world. In this study, an attempt was made to model the flow dynamics of blood in abnormally narrowed artery. Finite volume solver FLUENT was used for the analysis with the aim of understanding the consequences of increasing the degree of stenosis using a two-equation turbulence model. The compliant nature of the artery was neglected, and Newtonian behavior of the blood flow was assumed for the larger arteries. Steady-flow simulations with 75% area reductions were used to establish the validity of the current models by employing the standard and transitional variant of the k -w turbulence models. Subsequently, it was found that transitional k -w model was suitable for the low Reynolds number internal flows associated with the transition to turbulence, although only a minor departure in terms of the turbulence intensity peak was observed. Unsteady blood flow was introduced by employing a sinusoidal pulsatile waveform at the inlet. The pulsatile nature of the blood flow was investigated in the range of the constriction ratio from 60% to 90%, with an inlet-specified pulse. It was hypothesized that the severity of the stenosis played a major role in the initiation of the turbulence, since no major turbulence was reported for the 60% and 75% area reductions, while increasing the constriction ratio of 90% significantly altered the flow dynamics and triggered the transition to turbulence much earlier than anticipated. The outcome of current numerical efforts was expressed in terms of wall shear stress, a hemodynamically relevant parameter.
Book Synopsis Modeling of Blood Flow in Stenosed LAD Coronary Artery by : Zahraa A. Al-Saffar
Download or read book Modeling of Blood Flow in Stenosed LAD Coronary Artery written by Zahraa A. Al-Saffar and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atherosclerosis is the most common causes of vascular diseases.So;looking for the physical factors and correlations that explain the phenomena of existence the atherosclerosis disease in LAD artery in some people rather than the others is achieved in this study by analysis data from coronary angiography as well as estimating the blood velocity from coronary angiography scans without having a required data on velocity by using some mathematical equations and physical laws. It found some information that may explain the ability of small arteries to develop the lesions with time mainly in proximal site of LAD artery. For investigation the fluid-structural response to pulsatile Newtonian and non-Newtonian blood flow through an axisymmetric stenosed coronary artery;the simulation is built up by using ANSYS11 to evaluate the biomechanical parameters in the atherosclerotic process. Rigid and Newtonian cases were investigated to provide an understanding on the effects of incorporating Fluid-Structural Interaction (FSI) into model. non-Newtonian Carreau model was investigated with FSI. For validation of the models and methods used, the computation results are compared with previous studies.

Download or read book Computational Hemodynamics – Theory, Modelling and Applications written by Jiyuan Tu and published by Springer. This book was released on 2015-02-24 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses geometric and mathematical models that can be used to study fluid and structural mechanics in the cardiovascular system. Where traditional research methodologies in the human cardiovascular system are challenging due to its invasive nature, several recent advances in medical imaging and computational fluid and solid mechanics modelling now provide new and exciting research opportunities. This emerging field of study is multi-disciplinary, involving numerical methods, computational science, fluid and structural mechanics, and biomedical engineering. Certainly any new student or researcher in this field may feel overwhelmed by the wide range of disciplines that need to be understood. This unique book is one of the first to bring together knowledge from multiple disciplines, providing a starting point to each of the individual disciplines involved, attempting to ease the steep learning curve. This book presents elementary knowledge on the physiology of the cardiovascular system; basic knowledge and techniques on reconstructing geometric models from medical imaging; mathematics that describe fluid and structural mechanics, and corresponding numerical/computational methods to solve its equations and problems. Many practical examples and case studies are presented to reinforce best practice guidelines for setting high quality computational models and simulations. These examples contain a large number of images for visualization, to explain cardiovascular physiological functions and disease. The reader is then exposed to some of the latest research activities through a summary of breakthrough research models, findings, and techniques. The book’s approach is aimed at students and researchers entering this field from engineering, applied mathematics, biotechnology or medicine, wishing to engage in this emerging and exciting field of computational hemodynamics modelling.

Book Synopsis Mathematical Modeling of Blood Flow Through Stenosed Arteries by : Mohammed Musad
Download or read book Mathematical Modeling of Blood Flow Through Stenosed Arteries written by Mohammed Musad and published by LAP Lambert Academic Publishing. This book was released on 2012-04 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: In mathematical bio-sciences we study the applications of mathematical modeling and mathematical techniques to get an insight into the problems of bio-sciences. The mathematical model is a comprehensive process of representing real Phenomena in terms of Mathematical Equations, and extracting from them useful information for understanding and predicting the process of idealization. The study of blood flow characteristics in human circulatory system in the presence of stenosis, has been the subject of researchers in recent years. A serious study of this problem has been done by Young 1968 who presented a mathematical model to analyses theoretically the effects of stenosis on flow characteristics of blood and concluded that the resistance to the flow and the wall shear stress increase with the increase in stenosis size. The blood flow through large arteries considered as Newtonian flow by Lee JS 1974. while the blood flow through small arteries is considered as non-Newtonian by Chan et all 2007.

Download or read book Biodynamics written by Y. C. Fung and published by Springer Science & Business Media. This book was released on 2013-04-18 with total page 413 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a continuation ofmy Biomechanics.The first volume deals with the mechanical properties of living tissues. The present volume deals with the mechanics ofcirculation. A third volume willdeal with respiration, fluid balance, locomotion, growth, and strength. This volume is called Bio dynamics in order to distinguish it from the first volume. The same style is followed. My objective is to present the mechanical aspects ofphysiology in precise terms ofmechanics so that the subject can become as lucid as physics. The motivation of writing this series of books is, as I have said in the preface to the first volume, to bring biomechanics to students ofbioengineer ing, physiology, medicine, and mechanics. I have long felt a need for a set of books that willinform the students ofthe physiological and medical applica tions ofbiomechanics,and at the same time develop their training in mechan ics. In writing these books I have assumed that the reader already has some basic training in mechanics, to a level about equivalent to the first seven chapters of my First Course in Continuum Mechanics (Prentice Hall, 1977). The subject is then presented from the point of view of life science while mechanics is developed through a sequence of problems and examples. The main text reads like physiology, while the exercises are planned like a mechanics textbook.The instructor may filla dual role :teaching an essential branch of life science, and gradually developing the student's knowledge in mechanics.
