Research on neutron diffusion coupling calculation based on the UDS and UDF functions of FLUENT and its application analysis on fast reactor

四川大学学报. 自然科学版, 2020
With the great improvement of computer performance, analyzing the complex flow and heat transfer phenomenon by coupling CFD and neutronics has attracted lots of attentions nowadays. The study aims to investigate the neutron diffusion coupling calculation

Wiederherstellung chiraler Symmetrie und des Deconfinements in Neutronensternen [PDF]

, 2009
Neutron stars are very dense objects. One teaspoon of their material would have a mass of five billion tons. Their gravitational force is so strong that if an object were to fall from just one meter high it would hit the surface of the respective neutron

A high-resolution neutron diffraction and electron diffraction study of the structure and phase transitions in AgTaO3

APL Materials
The high temperature phase transition behavior of the quantum paraelectric material, AgTaO3, has previously been debated in the literature. To elucidate the phase transitions of AgTaO3, we used neutron powder diffraction and established the phase ...

Effect of Finite-temperature β-decay Rates on the Rapid Neutron Capture Process

The Astrophysical Journal
β -decay is known to play an essential role in the rapid neutron capture process ( r -process) during ( n ,  γ ) ↔ ( γ ,  n ) equilibrium and freeze-out when the neutron-rich nuclei decay back to stability.

An investigation into the growth and characterisation of thin film radioluminescent phosphors for neutron diffraction analysis [PDF]

, 2010
This investigation studied the growth and characterisation of thin film phosphors to examine the feasibility of enhancing a solid-state neutron scintillation detector system for increased detection resolution and detection rate.

Neutron stars and their terrestrial analogues

, 2014
When we consider in detail the behaviour of a fluid consisting of two (or possibly more) interpenetrating components, the likelihood of dynamical instabilities induced by coupling between the two fluids cannot be ignored. The phenomenon is generic to all

Neutron diffraction at simultaneous high temperatures and pressures, with measurement of temperature by neutron radiography

Mineralogical Magazine, 2001
AbstractThe commissioning and operation of apparatus for neutron diffraction at simultaneous high temperatures and pressures is reported. The basic design is based on the Paris-Edinburgh cell using opposed anvils, with internal heating. Temperature is measured using neutron radiography. The apparatus has been shown in both on-line and off-line tests to
