Development Of Meshless Computational Fluid Dynamics Methods

Summary 

In classical computational fluid dynamics (CFD), the fluid space is modelled by a fixed (Eulerian) mesh of many finite volume cells. This paradigm has been highly successful but requires special adaptations to handle moving walls (such as the leaflets of a heart valve) or dynamic interfaces (such as the surface of an ocean wave). In meshless methods such as Smoothed Particle Hydrodynamics and the Finite Volume Particle Method, the fluid is discretised by virtual "particles" that move with the flow and automatically track interfaces. The NUI Galway research group has made significant advances in these methods, including boundary conditions, fundamental numerics, and application to medical devices. This work has been funded by the Irish Council and the FP7 FET-Open programme as part of the NextMuSE collaboration.
