Experimental investigation of emission characteristics based on new alcohol-based gasoline fuel

open access: yesAdvances in Mechanical Engineering, 2017
This article chose the new type alcohol-based fuel as the engine fuel, realized lean burn in a CA4GA5 engine, and got the lean burn limit to 20.6. Taking the gasoline as equivalent fuel, and according to 10%, 20%, and 30% volume proportion of alcohol ...

3D Cruise Trajectory Optimization Inspired by a Shortest Path Algorithm

open access: yesAerospace, 2020
Aircrafts require a large amount of fuel in order to generate enough power to perform a flight. That consumption causes the emission of polluting particles such as carbon dioxide, which is implicated in global warming.

Effect of nonuniform density structure on burn-up ratio of multi-shock-compressed DT fuel in fast ignition

open access: yesNuclear Fusion
The burn characteristics of multi-shock-compressed DT fuel under fast ignition conditions are investigated using two-dimensional burn simulations. In solid-sphere implosions, high fuel areal density can be achieved through multi-shock compression with ...

Density Measurement of Irradiated and Nonirradiated Zirconium Oxide by Ptychographic X‐Ray Computed Tomography (PXCT)

open access: yesAdvanced Engineering Materials, EarlyView.
Mass density governs the protective behavior of oxide layers on nuclear fuel cladding. Ptychographic X‐ray computed tomography measures zirconium oxide grown on Zircaloy‐4 under reactor and autoclave conditions, revealing nearly identical bulk densities of 5.1 ± 0.80 g cm−3.
