Simulation of turbulent flow in a rapid compression machine: Large Eddy Simulation and computationally efficient alternatives for the design of ignition delay time experiments
(Elsevier, 2018-07-05)
Rapid compression machines (RCMs) are widely used by the fuel research community to provide engine-relevant conditions to study ignition delay time (IDT), which is a crucial target for validating chemical kinetic mechanisms ...
Incompressible moving boundary flows with the finite volume particle method
(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 ...
Analysis of shear-induced platelet aggregation and breakup
(Springer, 2015-07-31)
To better understand the mechanisms leading to the formation of thrombi of hazardous sizes in the bulk of the blood, we have developed a kinetic model of shear-induced platelet aggregation (SIPA). In our model, shear rate ...
Application of the meshless finite volume particle method to flow-induced motion of a rigid body
(ScienceDirect, 2013-10-01)
We present a new approach to numerical modelling of incompressible flow of fluid about an elastically mounted rigid structure with large body motions. The solution is based on the Finite Volume Particle Method (FVPM), a ...
Development of the meshless finite volume particle method with exact and efficient calculation of interparticle area
(Elsevier, 2014-02-18)
The Finite Volume Particle Method (FVPM) is a meshless method based on a definition of interparticle area which is closely analogous to cell face area in the classical finite volume method. In previous work, the interparticle ...
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
(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 ...
High-resolution measurement of the unsteady velocity field to evaluate blood damage induced by a mechanical heart valve
(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 ...
Extensions of the meshless finite volume particle method (FVPM) for static and dynamic free-surface flows
(Elsevier, 2018-10-04)
The Finite Volume Particle Method (FVPM) is a meshless method that incorporates features of both Smoothed Particle Hydrodynamics and the Finite Volume Method. Here, two new formulations are presented which enhance its ...
A model for surface tension in the meshless finite volume particle method without spurious velocity
(Elsevier, 2018-11-22)
A surface tension model has been developed in the finite volume particle method (FVPM). FVPM is a conservative, consistent, meshless particle method that incorporates properties of both smoothed particle hydrodynamics and ...
High-resolution measurements of leakage flow inside the hinge of a large-scale bileaflet mechanical heart valve hinge model
(Springer, 2019-06-24)
Purpose It is believed that non-physiological leakage flow through hinge gaps during diastole contributes to thrombus formation in Bileaflet Mechanical Heart Valves (BMHVs). Because of the small scale and difficulty of ...
