How do the principal components of hydrogen-air combustion under normal conditions change with temperature and pressure? 


Best insight from top research papers

The principal components of hydrogen-air combustion under normal conditions change with temperature and pressure. At higher temperatures, the flame shape and combustion zone length are affected by the deterioration in the fuel-oxidizer mixing process . The flame propagation velocity and pressure rise are dependent on the initial temperature, with increasing initial temperature leading to higher velocities and decreasing peak pressures . Reactions in combustion systems, including dissociations and isomerizations, are influenced by temperature, pressure, and the nature of the bath gas . The laminar burning velocity and explosion characteristics of ammonia-air mixtures are influenced by the equivalence ratio, initial premix temperature, and initial premix pressure . The cellularity density of hydrogen-air flames increases as the mixture becomes leaner, and trends in cellularity density are also observed with increasing initial pressure and temperature .

How does temperature affect combustion of wood and so PM?5 answersTemperature plays a crucial role in the combustion of wood and the formation of particulate matter (PM). Research indicates that in residential wood combustion, higher ground temperatures lead to aerosol pollution events due to shallow temperature inversions, significantly increasing equivalent black carbon (eBC) and PM concentrations. Similarly, in coal combustion, the reaction temperature influences PM characteristics, with optimal temperatures recommended to control PM emissions. Moreover, sampling temperature affects PM properties, shifting mass size distributions and elemental compositions, especially in the presence of alkali and alkaline earth metals. Additionally, during coal combustion, increasing temperatures result in more PM10 formation, with different mineral elements playing distinct roles in PM formation based on their occurrence forms. Therefore, controlling and optimizing combustion temperatures are essential to mitigate PM emissions from wood and coal combustion processes.
Hydrogen is cooled to cryogenic temperatures (typically around -200°C) and then compressed to pressures between 200 and 350 bar?5 answersHydrogen is indeed cooled to cryogenic temperatures for various applications. Different cooling technologies are explored to enhance efficiency. One innovative approach involves using a cryogenic refrigerator to actively cool liquid hydrogen, ensuring long-term lossless storage. Additionally, a study discusses the design of a cryogenic cooling system for an electric propulsion system utilizing liquid hydrogen as a refrigerant, highlighting the stability achieved in liquefying hydrogen at around 30 K. Furthermore, a novel solution using a thermoacoustic flow-through cooler is considered to cool hydrogen efficiently, with the added benefit of facilitating the conversion between ortho and para isomers of hydrogen. These advancements in cooling technologies play a crucial role in enabling the compression of hydrogen to high pressures for various industrial applications.
How hot can a hydrogen combustion engine can get without coolant?5 answersA hydrogen combustion engine can reach temperatures up to 1713°C at the exit of the first section and up to 1386°C at the exit of the second section, depending on the pressure in the combustion chamber. The cooling loss in hydrogen combustion is higher compared to methane combustion due to a thinner quenching distance and faster burning velocity, resulting in a higher cooling loss and lower thermal efficiency for hydrogen combustion. However, the specific temperature at which a hydrogen combustion engine can operate without coolant is not explicitly mentioned in the provided abstracts. Further research or specific data is needed to determine the maximum temperature a hydrogen combustion engine can reach without coolant.
What is the temperature of the exhaust gas of the hydrogen combustion engine.?4 answersThe temperature of the exhaust gas of a hydrogen combustion engine can be estimated using various methods. One method involves estimating the temperature by calculation using a sensor that measures the temperature of the exhaust gases and a preestablished model. Another method involves determining the exhaust gas temperature by measuring the lambda value of the exhaust gas and calculating a calculated exhaust gas temperature based on this value. Additionally, a method involves measuring the exhaust gas temperature with a temperature sensor and estimating the exhaust gas temperature based on the measured pressure value. Another method involves detecting the temperature of the exhaust gas after passing through an exhaust gas purification treatment device and calculating the temperature of the exhaust gas after passing through a second exhaust gas purification treatment device. Finally, an apparatus estimates the temperature of the exhaust gas based on the temperature increment caused by adiabatic compression and the amount of heat lost in the exhaust gas.
How hydrogen burn in an internal combustion engine?4 answersHydrogen burns in an internal combustion engine by being mixed with a fuel source, such as hydrocarbon fuel, and ignited to produce combustion. In some cases, hydrogen is injected directly into the cylinder of the engine, either alone or mixed with inlet gas, to achieve higher charging efficiency and thermal efficiency. In other cases, hydrogen is generated through a dehydrogenation reaction, where organic hydride-containing fuel is separated into hydrogen and dehydrogenated fuel. The hydrogen is then supplied to the engine, either alone or in combination with the dehydrogenated fuel, to power the combustion process. The combustion of hydrogen in the engine results in increased power output, high response speed, and improved combustion efficiency, while reducing exhaust emissions.
