Comment on "Prosthetic heart valves' mechanical loading of red blood cells in patients with hereditary membrane defects'', Grigioni et al.
Quinlan, Nathan J. (Elsevier, 2006-08-17) -
Effect of eddy length scale on mechanical loading of blood cells in turbulent flow
Dooley, Patrick N.; Quinlan, Nathan J. (2009)Non-physiological turbulent blood flow is known to occur in and near implanted cardiovascular devices, but its effects on blood are poorly understood. The objective of this work is to investigate the effect of turbulent ... -
Extension of the finite volume particle method to viscous flow
Nestor, Ruairi M.; Basa, Mihai; Lastiwka, Martin; Quinlan, Nathan J. (Elsevier, 2009-03-20)The finite volume particle method (FVPM) is a mesh-free method for fluid dynamics which allows simple and accurate implementation of boundary conditions and retains the conservation and consistency properties of classical ... -
Incompressible moving boundary flows with the finite volume particle method
Quinlan, Nathan J.; Nestor, Ruairi M. (Elsevier, 2010-03-24)Mesh-free methods offer the potential for greatly simplified modeling of flow with moving walls and phase interfaces. The finite volume particle method (FVPM) is a mesh-free technique based on interparticle fluxes which ... -
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) -
Models of flow-induced loading on blood cells in laminar and turbulent flow, with application to cardiovascular device flow
Quinlan, Nathan J.; Dooley, Patrick N. (Springer, 2007-08)Viscous shear stress and Reynolds stress are often used to predict hemolysis and thrombosis due to flow-induced stress on blood elements in cardiovascular devices. These macroscopic stresses are distinct from the true ... -
Permeable and Non-reflecting Boundary Conditions in SPH
Lastiwka, Martin; Basa, Mihai; Quinlan, Nathan J. (Wiley, 2009-11)Inflow and outflow boundary conditions are essential for the application of computational fluid dynamics to many engineering scenarios. In this paper we present a new boundary condition implementation that enables the ... -
Scale-up of bileaflet mechanical heart valve for enhanced resolution of the unsteady flow field
Bellofiore, Alessandro; Donohue, Eilis M; Quinlan, Nathan J. (University of Limerick, 2009-01-30) -
Truncation error in mesh-free particle methods
Quinlan, Nathan J.; Basa, Mihai; Lastiwka, Martin (2006-06-25)A truncation error analysis has been developed for the approximation of spatial derivatives in smoothed particle hydrodynamics (SPH) and related first-order consistent methods such as the first-order form of the reproducing ...
