The present work is a collection of research work related to physiological fluid dynamics. It is an interdisciplinary field developed through interaction of scientists working in engineering, medicine and sciences. This interaction has resulted in the past in strengthening our knowledge in functional aspects of various biological and physiological systems and developments of devices which have helped in the alleviation of sufferings. This contributed volume is of immense value, to clinicians having interest in cardiovascular blood flow, to experimentalists for designing new techniques and to theoreticians with a keen interest to develop new analytical procedures.
