| Abstract | |
Incompressible Smoothed Particle Hydrodynamics (ISPH) method is a meshless approximation that has been used to simulate several types of fluid flows, through a finite particle set and fully lagrangian formulation. The application of ISPH method in two-fluid flow simulations however, has presented many challenges, specially related to the presence of the interface between different fluids. Thus, we present in this study the development of a numerical code based on ISPH, introducing novel interface treatment techniques. A thorough study about this method is provided, considering different methodologies and analysing specific points such as the position of the interface and the obtained pressure field. Results have been presented to show the methods developed in this thesis efficiently simulate two-fluid flows, illustrating the improvements achieved by the proposed interface treatment techniques. Finally, a study of biphasic mixture behavior is carried out with reference to phase inversion phenomena (AU) | |
