요약 | A Lagrangian scheme that combines Voronoi diagrams with smoothed particle hydrodynamics (SPH) for incompressible flows has been developed. Within the Voronoi tessellation, the differential operators are discretized by adding contributions from n |
요약 | The Voronoi cells allow enforcing the boundary conditions directly on the portion of their perimeter in contact with the boundary. Two sub-domains are then defined based on the proximity to the boundaries. The VPH formulation is used in those pa |
요약 | The unbounded nature of Voronoi tessellations requires further treatment close to boundaries and free-surfaces to ensure that the Voronoi cells associated with the particles do not extend beyond the fluid domain. Boundaries are discretized as se |
요약 | The delta-SPH correction proposed by Cercos-Pita et al., Applied Math. Modelling, 40(19), 2016, is extended to the VPH formulation. In addition, the density field is reinitialized every certain number of time steps following the scheme proposed |
요약 | The code key subroutines are written in C++, and the main time-stepping program is implemented in Matlab. A leap-frog numerical scheme is used to iterate forward in time. The program architecture is summarized graphically, with a detailed analys |
요약 | The method presented in this thesis is suitable for free-surface flows with moving solid boundaries within the fluid domain. However, prior to extending it to such complicate problems, the accuracy of the coupled scheme is discussed by means of |
