On the non-slip boundary condition enforcement in SPH methods. [PDF]

, 2011
The implementation of boundary conditions is one of the points where the SPH methodology still has some work to do. The aim of the present work is to provide an in-depth analysis of the most representative mirroring techniques used in SPH to enforce ...

Pattern recognition issues on anisotropic smoothed particle hydrodynamics

, 2013
This is a preliminary theoretical discussion on the computational requirements of the state of the art smoothed particle hydrodynamics (SPH) from the optics of pattern recognition and artificial intelligence.

Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications

The Anatomical Record, EarlyView.
Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

Comparison of multiphase SPH and LBM approaches for the simulation of intermittent flows

, 2019
Smoothed Particle Hydrodynamics (SPH) and Lattice Boltzmann Method (LBM) are increasingly popular and attractive methods that propose efficient multiphase formulations, each one with its own strengths and weaknesses.

Repeating Nuclear Transients From Repeating Partial Tidal Disruption Events

Astronomische Nachrichten, EarlyView.
ABSTRACT Extragalactic nuclear transients that exhibit repeating outbursts can be modeled as the repeated dynamical interaction between bound stars and supermassive black holes (SMBHs). A subset of these transients, with recurrence timescales of months‐to‐years, have been explained as accretion flares from the repeated tidal stripping of a star by an ...

Simple free-surface detection in two and three-dimensional SPH solver [PDF]

, 2013
A simple free-surface particle detection method for two and three-dimensional SPH simulation has been implemented. The method uses sphere representation for the SPH particle. The fluid domain is covered by overlapping spheres.

Nuclear Star Clusters and the Stellar Spheroids of their Host Galaxies

, 2012
(Abridged) We combine published photometry for the nuclear star clusters (NSCs) and stellar spheroids of 51 low-mass, early-type galaxies in the Virgo cluster with empirical mass-to-light ratios, in order to complement previous studies that explore the ...

High‐Temperature Heat Pump Test Bench with n‐Butane (R‐600) Generating Steam

Chemie Ingenieur Technik, EarlyView.
This work involves building a test bench for a high‐temperature heat pump (HTHP) and analyzing the measurements. The focus is on steam generation using an HTHP to decarbonize process steam demand. The findings indicate that stable steam generation is possible, providing a higher heat transfer coefficient in the heat pump's condenser.

SPH Modelling of Hydrodynamic Lubrication along Rough Surfaces

Lubricants, 2019
Rough and textured surfaces are of paramount importance for lubrication, both in nature and in technology. While surface roughness relevantly influences both friction and wear, artificial surface texturing improves the performance of slider bearings as ...

Spontaneous Perirenal Hemorrhage Mimicking Renal Rupture in a Long‐Term Hemodialysis Patient: A Case Report [PDF]

Clin Case Rep
ABSTRACT Spontaneous perirenal hemorrhage (SPH) and spontaneous renal rupture (SRR) are rare emergencies that can be radiologically indistinguishable when hematomas are large, especially in hemodialysis patients. We report a 53‐year‐old man on long‐term hemodialysis who developed acute left flank pain 19 h after low‐molecular‐weight heparin.
