Experimental Study on the Effects of Oxygen Concentration and Thermal Radiation on the Combustion Characteristics of Wood Plastic Composites at Low Pressure

Fire
The use of artificial oxygenation to counteract the effects of hypoxia and improve living standards in high-altitude, low-oxygen settings is widespread. A recognized consequence of this intervention is that it elevates the risk of fire occurrence.

Pyrolysis Oil Derived from Plastic Bottle Caps: Characterization of Combustion and Emissions in a Diesel Engine

Energies, 2023
Recycling used plastic can help reduce the amount of plastic waste generated. Existing methods, namely the process of pyrolysis, are chemical heating processes that decompose plastics in the absence of oxygen. This decomposes the plastics in a controlled

Turbulence characteristics in Internal Combustion Engines

Bulletin of JSME, 1982
The velocity of gas flow in the combustion chambers of two engines was measured, and the turbulence characteristics were investigated. It is shown that the auto-correlation coefficient of the fluctuating component of velocity and the normalized one-dimensional energy spectral density of turbulence are nearly determined by the integral time scale of ...

Characteristic phenomena in combustion [PDF]

Discrete Dynamics in Nature and Society, 1997
For the case of a reaction–diffusion system, the stationary states may be represented by means of a state surface in a finite‐dimensional state space. In the simplest example of a single semi‐linear model equation given. in terms of a Fredholm operator, and under the assumption of a centre of symmetry, the state space is spanned by a single state ...
