Inviscid SPH

open access: yes, 2010
In smooth-particle hydrodynamics (SPH), artificial viscosity is necessary for the correct treatment of shocks, but often generates unwanted dissipation away from shocks. We present a novel method of controlling the amount of artificial viscosity, which uses the total time derivative of the velocity divergence as shock indicator and aims at completely ...

Open-source software for modelling of free surface flows

open access: yesТруды Института системного программирования РАН, 2018
Problems of free-surface flow of viscous incompressible fluid are very useful in different practical cases. There are many specifies and limitations in these problems which are critically important for correct solving.

A SPH Model for Incompressible Turbulence

open access: yesProcedia IUTAM, 2015
A coarse-grained particle model for incompressible Navier-Stokes (NS) equation is proposed based on spatial filtering by utilizing smoothed particle hydrodynamics (SPH) approximations. This model is similar to our previous developed SPH discretization of NS equation ({\it Hu X.Y. & N.A. Adams, J. Comput.

Comparative analysis of numerical solutions of 2D unsteady dambreak waves using FVM and SPH method

open access: yesJournal of Hydrology and Hydromechanics, 2023
This work presents a comparison of two-dimensional numerical solutions of unsteady free surface flow. This is a simulation of the dam-break wave with different configurations using based-mesh finite volume method and meshless smoothed particle ...

FEM or SPH ?

open access: yesJournal of Engineering Sciences and Innovation, 2016
This paper brings, in front of the reader, some aspects regarding the using of those numerical methods, perhaps most used, for analysis of the fluids and structures. Next to the FEM (Finite Element Method), new numerical methods appeared, among these, the methods named meshfree methods are nowadays most used.

MicroCT reinvestigation of the only articulated fossil anostomid fish reveals synonymy of Arhinolemur Ameghino, 1898 and Megaleporinus Ramirez et al., 2017

open access: yesThe Anatomical Record, EarlyView.
Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.

Description of large, well‐preserved Enchodus specimens from the Bearpaw Formation of Alberta, Canada

open access: yesThe Anatomical Record, EarlyView.
Abstract Fishes of the genus Enchodus were abundant and cosmopolitan in the Late Cretaceous, but are primarily known from isolated remains in Canada. Four well‐preserved fish skulls were recovered in recent years from ammolite mines sampling the Bearpaw Formation of Southern Alberta, and are here referred to Enchodus petrosus Cope, 1874.

Fuel Tank Vertical Sloshing during Aircraft Landing

open access: yesXibei Gongye Daxue Xuebao, 2020
In this article, the influence of the fuel sloshing on the tank under the landing condition is investigated to explain the skin deformation of wing tank. Based on the SPH method, a simplified fuel tank model of gas-liquid-solid three-phase is established.

Codeine toxicity via breast Milk: Can this occur and implications for opiate therapy in children

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Codeine is commonly used in combination analgesic products. The use of codeine during breastfeeding can rarely be associated with serious adverse effects related to genetic polymorphisms affecting codeine's metabolism and disposition. Clinicians treating infants of breastfeeding mothers should be aware of this rare but potentially serious complication.
