High-resolution measurement of the unsteady velocity field to evaluate blood damage induced by a mechanical heart valve
Bellofiore, Alessandro; Quinlan, Nathan J. (Springer, 2011-09)We investigate the potential of prosthetic heart valves to generate abnormal flow and stress patterns, which can contribute to platelet activation and lysis according to blood damage accumulation mechanisms. High-resolution ... -
Measurement of cardiovascular device flow at scales approaching cell size
Bellofiore, Alessandro; Quinlan, Nathan J. (2009-09-24) -
Microscale flow structures measured downstream of a mechanical heart valve
Bellofiore, Alessandro; Quinlan, Nathan J. (Trinity College Dublin, 2010-01-22) -
Scale-up of an unsteady flow field for enhanced spatial and temporal resolution of PIV measurements: application to leaflet wake flow in a mechanical heart valve
Bellofiore, Alessandro; Donohue, Eilis M.; Quinlan, Nathan J. (Springer, 2011-07)A scale-up approach is developed to enhance effective spatial and temporal resolution of PIV measurements. An analysis shows that complete similarity can be maintained for certain unsteady flows and that all types of error ... -
