• Resumen

  • This thesis covers the implementation of a new tool to solve fluid problems capable of solving free-surface and fluid-solid interfaces. This tool is based on a Semi-Lagrangian Particle Finite Element Method (SL-PFEM) approach of solve the Navier-Stokes equations. In a similar fashion to the Particle Finite Element Method (PFEM) and its second generation version (PFEM-2), Lagrangian particles are used to solve the convection problem while a background mesh is used to solve the elliptic part of the Navier-Stokes equations. One of the objectives is that the tool must be efficient when calculating problems. This is managed by first developing the numerical scheme so that it is second order accurate in time and space and then optimising the implementation so that it can perform well in HPC environments.

    To solve the general interface problems such as fluid-fluid, fluid-solid or the two combined, then an enrichment method is applied to the scheme. This, joined with an SL-PFEM variation of the Level-Set Method allows to accurately capture and compute these types of problems. This implementation leads to the ability to solve multi-body problems that can interact with multiple fluids.
