Mesh-free Lagrangian Modelling of Fast Flow Dynamics

摘要

Smoothed Particle Hydrodynamics (SPH) is a relatively new meshlessnumerical approach which has attracted significant attention in the lasttwo decades. Compared with the conventional mesh-dependentcomputational fluid dynamics (CFD) methods, the SPH approachexhibits unique advantages in modeling multiphysics fluid flows andassociated transport phenomena due to its capabilities of handlingcomplex material surface behavior as well as modeling complicatedphysics in a relatively simple manner. On the other hand, as SPH isstill a developing CFD tool, it is vital to investigate its attributes,namely, advantages or potential limitations in modeling differentmultiphysics flow problems to further understand and then improvethis technique for real life phenomena and industrial applications.Toward this end, this work aims to explain the motivations behindutilizing SPH method, recent industrial applications of this technique,as well as challenges in order to make it as an hand-on computationaltool.
