Measurement and scaling of turbulent burning velocity of ammonia/methane/air propagating spherical flames at elevated pressure

Hongchao Dai et al.

Summary: This study presents the accurate laminar burning velocity, turbulent burning velocity, and their correlations for ammonia/methane/air propagating spherical flames. The results indicate that the turbulent burning velocity decreases with the ammonia content, while the normalized turbulent burning velocity increases. It is also found that the turbulent burning velocity of ammonia flame can be expressed using the correlation of Karlovitz and Damkohler numbers.

Effects of cloud size and built-in obstacles on hydrogen cloud explosion using large eddy simulation

Yanchao Li et al.

Summary: The purpose of this study is to evaluate hydrogen cloud explosion using large eddy simulation. The research found that the LES model combined with acoustical theory could reproduce flame acceleration and explosion pressure evolution. It was also observed that increasing cloud scale resulted in higher maximum explosion pressure and maximum flame front velocity. In addition, the introduction of obstacles increased the growth rate of flame front velocity and explosion pressure.

Experimental and kinetic modeling study of the laminar burning velocity of NH3/DME/air premixed flames

Huahua Xiao et al.

Summary: This study presents an experimental and kinetic modeling investigation of the laminar burning velocity and chemical kinetics of NH3/DME/air mixtures. The results show that increasing the DME fraction enhances the burning velocity, while the initial pressure has a negative influence. The developed reaction mechanism performs well in predicting the combustion performance of different mixtures.

Experimental and numerical study of the laminar burning velocity of NH3/H2/air premixed flames at elevated pressure and temperature

Bao-zhi Jin et al.

Summary: Ammonia is a carbon-free fuel with ideal production and storage systems, showing great research prospects. Experimental data revealed that the laminar burning velocity of NH3/H-2/air flame increases with increasing hydrogen ratios and temperature, but decreases with increasing pressure. The equivalent ratio of the maximum laminar burning velocity is only affected by the proportion of reactants.

Propagation of Darrieus-Landau unstable laminar and turbulent expanding flames

Xiao Cai et al.

Summary: The experimental study investigates the propagation of laminar and turbulent expanding flames under Darrieus-Landau instability using stoichiometric H-2/O-2/N-2 flames in a medium-scale, fan-stirred combustion chamber. It was found that turbulence accelerates the flame propagation and induces additional wrinkles, advancing the onset of acceleration stages. The interaction between DL instability and turbulence is identified as the corrugated flamelets regime, facilitating flame propagation even in intense turbulence.

The experiment study to assess the impact of hydrogen blended natural gas on the tensile properties and damage mechanism of X80 pipeline steel

Dengji Zhou et al.

Summary: This study qualitatively investigated the degradation mechanism of X80 steel in hydrogen blended natural gas environment through experimental research. It was found that an increase in hydrogen proportion significantly affects the mechanical properties of specimens, with more serious impact on notched specimens. This provides a basis for determining a safe hydrogen proportion for X80 pipeline steel when transporting hydrogen blended natural gas.

Effect of vent area on vented deflagration of hydrogen-methane-air mixtures

Wei Liu et al.

Summary: The study investigated the effect of vent area on the deflagration of hydrogen-methane-air mixtures in a vertical duct, finding that the nondimensional vent coefficient had varying impacts on flame evolution and pressure buildup. Different K-v values led to differences in pressure distribution inside and outside the duct, with external explosions affecting internal deflagrations to a lesser extent at higher K-v values.

Evaluation of unrestricted hydrogen and hydrogen-methane explosion venting through duct

Yanchao Li et al.

Summary: The study focuses on evaluating unrestricted duct-vented explosion of hydrogen-air mixture and hydrogen-methane-air mixture. It shows that chocked venting could be achieved and maximum explosion pressure and pressure rise rate can be significantly reduced by unrestricted duct-venting. Maximum explosion pressure and pressure rise rate for hydrogen explosion venting increase with equivalence ratio until phi = 1.5.

Characteristics of hydrogen-ammonia-air cloud explosion

Yanchao Li et al.

Summary: This study focuses on the characteristics of hydrogen-ammonia-air cloud explosions, experimentally revealing the correlation between flame behavior and explosion pressure, as well as analyzing the factors affecting laminar burning velocity. The results show that flame propagation velocity and maximum explosion pressure decrease with increasing ammonia fraction, while they initially increase and then decrease with increasing equivalence ratio.

Flame structure, turbulent burning velocity and its unified scaling for lean syngas/air turbulent expanding flames

Haoran Zhao et al.

Summary: A systematic experimental study was conducted on lean premixed syngas/air turbulent expanding flames with varying turbulence intensities, initial pressures, and hydrogen volumetric fractions. Results showed that increasing turbulence intensity and initial pressure resulted in refined and wrinkled flames, leading to larger flame areas and higher turbulent burning velocities. The rise in hydrogen fraction also significantly enhanced the burning velocity due to the promotion of laminar burning velocity and diffusional-thermal instability. The study also found a unified scaling of turbulent burning velocity, indicating a practical method to correlate turbulent Reynolds number with Lewis number close to unity. Additionally, expanding flames exhibited a self-similar propagation law with a quantitative dependence of turbulent burning velocity with flame expansion.
