A model for surface tension in the finite volume particle method without parasitic current
(NUI Galway, 2018-06-26)
A surface tension model has been developed in the finite volume particle method (FVPM). Surface tension force is applied only on free-surface particles, which are inexpensively and robustly detected using the FVPM ...
Simulation of turbulent flow in a rapid compression machine: Large Eddy Simulation and computationally efficient alternatives for the design of ignition delay time experiments
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 ...
Extension of the finite volume particle method to viscous flow
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 ...
Models of flow-induced loading on blood cells in laminar and turbulent flow, with application to cardiovascular device flow
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 ...
Incompressible moving boundary flows with the finite volume particle method
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 ...
Effect of eddy length scale on mechanical loading of blood cells in turbulent flow
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 ...
Permeable and Non-reflecting Boundary Conditions in SPH
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 ...
Truncation error in mesh-free particle methods
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 ...
