A brief description of the Smoothed Particle Hydrodynamics method is presented together with some test calculations and astrophysical examples of accretion phenomena.

Coastal protections, such as dykes, seawalls, breakwaters and natural beaches can often be considered porous structures. The accurate prediction of wave motion around structures is necessary for the effective design durable coastal protections.

We present the general analytic solution of a viscous gas ring around a central mass. This solution is used to test a further development of the smoothed particle hydrodynamics (SPH) algorithm, which is capable of simulating problems with physical viscosity (here: with kinematic viscosity). We discuss some SPH simulation results and conclude some fundamental properties of the algorithm. c © 199...

Abstract We comment on a recent article [Comput. Mech. 2020, 65, 487–502] about surface-tension modeling for free-surface flows with Smoothed Particle Hydrodynamics. The authors motivate part of their work related to novel principal curvature approximation by the wrong claim that classical formulation in SPH overestimates 3D factor 2. In this note we confirm correctness and point out misconcept...

Low-temperature heat capacities from 5 to 350 K by adiabatic calorimetry and high-temperature enthalpy increments above 450 K by drop calorimetry of high-purity Sr(OH), and /I-Ba(OH), have been measured. From the results, smoothed thermochemical and thermophysical functions of the two compounds have been tabulated at selected temperatures.

We introduce a simple and efficient algorithm for diffusion in smoothed particle hydrodynamics (SPH) simulations and apply it to the problem of chemical mixing. Based on the concept of turbulent diffusion, we link the diffusivity of a pollutant to the local physical conditions and can thus resolve mixing in space and time. We apply our prescription to the evolution of an idealized supernova rem...

Smoothed Particle Hydrodynamics (SPH) is a computational technique for the numerical simulation of the equations of fluid dynamics without the use of an underlying numerical mesh. Although originally developed for use in astrophysical gas dynamics, SPH has recently been applied to many other areas of numerical fluid dynamics and materials modelling, several of which have particular relevance to...
