Performance optimization design of trapped vortex combustion chamber with a sand dune blunt body

open access: yesCase Studies in Thermal Engineering
In an effort to enhance the performance of the trapped vortex combustion chamber, this paper improved the trapped vortex combustion chamber and proposed a sand dune trapped vortex combustion chamber. Firstly, the effects of different inlet velocities and

Computational study of influence of inflow port channel design on spark-ignition natural gas engine parameters

open access: yesMATEC Web of Conferences, 2018
Resistance is The article presents the results of the research of a charge swirl motion influence on working process, engine parameters and NOx emissions of a spark ignition premixed natural gas engine. The charge swirl motion was organized by tangential

Gas turbine exhaust nozzle [PDF]

open access: yes, 1973
An elongated hollow string is disposed in an exhaust nozzle combustion chamber and communicates with an air source through hollow struts at one end. The other end of the string is bell-mouth shaped and extends over the front portion of a nozzle plug. The

Electrodialysis of LiPF6 in Aqueous Solution for Wastewater Treatment in Hydrometallurgical Recycling of Lithium‐Ion Batteries

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Hydrometallurgical recycling of lithium‐ion batteries produces wastewater containing PF6− and Li+, which must be removed and recovered, respectively. This study pioneers electrodialysis using anion exchange membrane and cation exchange membrane to separate PF6− and Li+.

Numerical study of acoustic oscillations and combustion instabilities in solid propellant rocket [PDF]

open access: yes, 1997
A numerical analysis of unsteady motions in solid rocket motors has been conducted. A fully coupled implicit scheme based on a dual time-stepping integration algorithm has been adopted to solve the governing equations and associated boundary conditions.

Bayesian Optimization Guiding the Experimental Mapping of the Pareto Front of Mechanical and Flame‐Retardant Properties in Polyamide Nanocomposites

open access: yesAdvanced Intelligent Discovery, EarlyView.
Bayesian optimization enabled the design of PA56 system with just 8 wt% additives, achieving limiting oxygen index 30.5%, tensile strength 80.9 MPa, and UL‐94 V‐0 rating. Without prior knowledge, the algorithm uncovered synergistic effects between aluminum diethyl‐phosphinate and nanoclay.

Clusters Stagnating During Condensation: Metastable Material or a Separate State of Matter?

open access: yesAnnalen der Physik, EarlyView.
Condensation stagnation, that is, the existence of a delay between nucleation and growth during the gas‐phase particle formation, is a crucial phenomenon, which manifests itself as the presence of supercritical clusters in resulting particulates. The light emission signature of stagnant clusters is identified in the magnesium particle flame in air, and,

Research on Suppression of Vibration Caused by Combustion Pressure Pulsation in Aircraft Engines

open access: yesShock and Vibration
Abnormal high-energy narrowband signals appeared in the aircraft engine test. By analyzing the characteristics of the vibration signals and the pressure pulsation signals in the measurement point data of the engine, it can be speculated that the abnormal
