In this study, a numerical weak coupling strategy for the modeling of a conjugate heat transfer phenomenon is considered. Where the incompressible Navier-Stokes equations are solved using the Semi-Implicit Method for Pressure Linked Equations (SIMPLE

To simulate fast transient phenomena, one must consult realistic compressible fluid models that take into consideration phase change, shock wave generation and its propagation. In an industrial framework, such phenomena occur mostly near industrial a

In the context of high fidelity simulation of compressible flows (LES and DNS) at extreme scale (small time steps) on massively parallel supercomputers, explicit time integration methods are widely used since they both have a good computational cost

This chapter examines how fully compressible smoothed particle hydrodynamics schemes perform in benchmark shock propagation problems. These problems involve media with discontinuous density distribution, discontinuous material parameters, as well as

This chapter refers to two different ways of deriving schemes for the smoothed particle hydrodynamics method. The first is based on Newtonian mechanics, while the second on Lagrangian mechanics. It becomes obvious that in order to extend smoothed par
