A dynamic combustion model for supersonic turbulent combustion
, 2023 Supersonic combustion plays a vital role in various applications, including scramjets, dual-mode ramjets, and pulse detonation engines. However, the flame characteristics can vary significantly, depending on the application. To model supersonic combustion, large eddy simulation coupled with a partially stirred reactor (PaSR) is commonly used.

Angewandte Chemie, EarlyView.This work develops a spray‐assisted in situ assembly technique to construct AHF materials with nitrogen/oxygen‐regulated one‐dimensional channels on glass fiber, providing abundant active sites and enabling rapid transport for lithium ions. Subsequently, phosphate flame retardants are encapsulated via in situ polymerization, resulting in a thermally ...

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Stabilization of combustion front in supersonic flow using streamer’s discharge
MATEC Web of Conferences, 2018 Thermodynamic analysis shows that for flights with velocities exceeding six sound velocities, it is required to burn fuel not in a subsonic but in a supersonic flow.

Ignition Characteristics of Supersonic Combustion
IOP Conference Series: Materials Science and Engineering, 2020 Abstract Detonation may be initiated by two different modes, direct initiation or deflagration-to- detonation transition (DDT). Direct initiation can occur by a strong source such as using exploding wire or high-voltage discharge jets. Nevertheless, this method required a significant amount of energy in order to ensure that the generated
