Flow analysis and uniformity evaluation of the exhaust pipeline of a marine diesel engine

open access: yesZhongguo Jianchuan Yanjiu, 2019
[Objectives]In a marine diesel engine,the SCR reactor's NOx conversion efficiency is effected by the flow field uniformity at the inlet. In order to optimize the design of the exhaust pipeline of the diesel engine and the improve the SCR reactor's ...

Formation of uniform magnetic flux distribution for NMR magnets using HTS bulk magnets activated by pulsed-field magnetization

open access: yesMaterials Research Express, 2020
Nuclear magnetic resonance (NMR) magnets generally need an extremely uniform magnetic field in the space where the specimens will be placed. Although high temperature superconducting bulk magnets can obtain an intense magnetic field of more than 3 T, the

A spatially uniform illumination source for widefield multi-spectral optical microscopy.

open access: yesPLoS ONE, 2023
Illumination uniformity is a critical parameter for excitation and data extraction quality in widefield biological imaging applications. However, typical imaging systems suffer from spatial and spectral non-uniformity due to non-ideal optical elements ...

The Dedekind different for a uniform set of points in Pn

open access: yesTạp chí Khoa học Đại học Huế: Khoa học Tự nhiên, 2022
Given a set of s distinct points X in the projective space Pn over a field K, we are interested in studying the uniformity of X. Explicitly, we work out an algorithm for checking the uniformity of X and we apply the Dedekind different to characterize ...

The Effect of Uniform and Non-Uniform Electric Fields on Flame Propagation

open access: yesJournal of Thermal Science and Technology, 2008
The purpose of this study is to elucidate flame propagation behavior under the application of uniform and non-uniform electric fields by using a constant volume vessel. Two electrodes are attached to the ceiling and the bottom of the combustion chamber and electric fields are applied in the direction of the chamber's vertical axis.
