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 ... -
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 ... -
Robustness and accuracy of SPH formulations for viscous flow
Quinlan, Nathan J.; Lastiwka, Martin; Basa, Mihai (2009)Numerous methods are available for the modelling of viscous stress terms in smoothed particle hydrodynamics (SPH). In this work, the existing methods are investigated systematically and evaluated for a range of Reynolds ... -
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 ...
