Fundamental studies of combustion of droplet and vapour mixtures [PDF]

, 2010
There are few experimental data of a fundamental nature that clearly demonstrate the similarities and differences in burning rates between single phase and two phase combustion, either in laminar or turbulent conditions. Such data are essential towards a

The Role of Molecule Clustering by Hydrogen Bond in Hydrous Ethanol on Laminar Burning Velocity

Journal of Combustion, 2016
The role of hydrogen bond molecule clustering in laminar burning velocities was observed. The water in hydrous ethanol can change the interaction between water-ethanol molecules. A certain amount of water can become oxygenated which increases the burning

Turbulent Flames Speeds and Laminar Burning Velocities of Dusts using the ISO 1 m³ Dust Explosion Method

Chemical Engineering Transactions, 2014
The ISO 1 m3 dust explosion vessel was instrumented with thermocouples acting as flame detectors. These were used with methane/air gas explosions to show that the explosion flame was spherical in the constant pressure phase of the explosion and that a ...

Flow field and local burning velocity affected by stretch in swirl flow of turbulent premixed flames

Journal of Thermal Science and Technology, 2022
In this study, we have investigated turbulent premixed flames affected by local stretch in a swirl flow, measured by the simultaneous OH-PLIF/SPIV system. Evaluating the transient of burning velocity and stretch rate, the flow and the flame dynamics in a

Thermal Calculations for Co‐Firing of Hydrogen/Ammonia and Coal in 660‐MW Coal‐Fired Boilers

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT To achieve a clean energy transition under the dual carbon goals, blending hydrogen/ammonia into pulverized coal boilers represents a key technological pathway. Different hydrogen/ammonia co‐firing ratios (5%–50%) are investigated for their impact on the thermodynamic characteristics of 660‐MW supercritical boiler at 100% and 20% boiler ...

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Laminar burning velocity of the dimethyl carbonate–air mixture formed by the Li-ion electrolyte solvent [PDF]

, 2020
If a Li-ion cell fails and the electrolyte leaks out into air, a flammable premixed gas cloud can be formed. The electrolyte combustion energy is 65–70% of the total energy content of the cell. The main objective of this study is to determine the laminar

STUDY OF THE EFFECT OF ELEVATED TEMPERATURES ON THE LAMINAR BURNING VELOCITY OF PROPANE-AIR MIXTURES

Diyala Journal of Engineering Sciences, 2015
Laminar burning velocities were obtained at wide equivalence ratios of propane –air mixtures. The effect of elevated temperatures was also analyzed. It was found that the laminar burning velocity is increased with the increase of temperature at constant
