Combustion Characteristics of Hydrogen

Journal of the Fuel Society of Japan, 1975
Hydrogen is considered as a very Promising material for the future energy system. When hydrogen is used as an energy carrier, hydrogen will be used as fuel gas for the burners in the industry and also in the houses. Therefore, it is important to discuss the problems about the combustion of hydrogen as a practical fuel.In this paper, the concerning ...

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 ...

A Novel Modified Petroresin Particle (MPRP) With Enhanced Oil–Water Selectivity for Cold Production in Heavy Oil Reservoirs

Advanced Functional Materials, EarlyView.
A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...

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.

Graphene Quantum Dot‐Induced Microstrain for Framework Stabilization of High‐Entropy Prussian Blue Analog in High‐Current Alkaline Hydrogen Evolution Reaction

Advanced Functional Materials, EarlyView.
The intrinsic distortion‐rich lattice of HEPBA with GQD‐enabled microstrain engineering establishes a mechanistic route toward high‐performance alkaline hydrogen evolution reaction. HEPBA inherently feature heterogeneous local coordination environments arising from multimetal incorporation, while properly introducing GQD during coprecipitation ...

Combustion Characteristics of Combustion Chamber Using Compost as a Fuel

Energy Procedia, 2014
AbstractThe aim of the present study is to develop the biomass furnace combustor which can effectively use the compost as a fuel. Here, the compost which is made from pig's waste and has the calorific value of 2000kcal/kg, is employed here. Emphasis is placed on the optimum conditions of fuel and air flow rates, moisture content of the compost and the ...

Ionic Precursors Transformed Into Vinyl Acetate Synthesis Catalyst via Reaction‐Driven Restructuring

Advanced Functional Materials, EarlyView.
This work demonstrates that a simple physical mixture of Pd and Au ionic precursors, KOAc promoter, and SiO2 support can transform into a highly active vinyl acetate synthesis catalyst through reaction‐driven restructuring. The results highlight reaction‐induced restructuring as an innovative and sustainable catalyst design strategy.
