Summary: The study investigated the confined explosion characteristics of ethyl acetate in a constant volume explosion vessel. It was found that the peak explosion pressure and the maximum pressure rise rate increased with higher initial pressure and lower initial temperature. Additionally, the explosion time decreased with decreasing initial pressure. The experimental and theoretical deflagration index of ethyl acetate were compared, showing different levels of hazard potential.

Summary: This study measured various values related to the explosion of propylene and nitrogen at 25 degrees Celsius. The results showed that the lower explosion limit did not significantly change with pressure increase, but the upper explosion limit did. Additionally, the presence of nitrogen decreased the explosion risk of propylene while also affecting other explosion-related parameters.

Summary: The research conducted explosion experiments on methane and air mixtures in a closed chamber at elevated pressure and temperature situations, providing useful data on the dependency of explosion risk parameters on pressure, temperature and gas concentration. The experimental results show that explosion pressure increases with initial pressure but slightly declines at elevated temperatures, while pressure rise rate and deflagration index increase at high pressures but lower at higher temperatures.

Summary: The study showed that H2-enriched syngas achieved maximum explosion pressure during stoichiometric explosions, while CO-enriched syngas was more sensitive to fuel-rich explosions. In the pressure rising process, flame propagation speed played a more crucial role in the evolution of pressure.

Summary: This study compared the abilities of three explosion inhibitors (Al(OH)(3), CaCl2, and NH4H2PO4) to prevent coal-dust explosions at mass fractions of 30 wt% and 50 wt%. The effects of these inhibitors on parameters characterizing the explosion intensity of pulverized coal were investigated. The results showed that increasing the mass fractions of CaCl2 and NH4H2PO4 reduced the explosion intensity, while increasing Al(OH)(3) did not. NH4H2PO4 exhibited the highest explosion suppression performance, followed by CaCl2 and Al(OH)(3).

Summary: This work experimentally investigates the role of flame-generated compression in the deflagration to detonation transition process. It quantifies the compression compared to other flame regimes and identifies the reactant conditions where flame-generated compression begins. The study provides detailed insight into the flame and flow field characteristics where the runaway process occurs.

Summary: This study observed the flame structure of outwardly propagating HCNG-30 premixed flames and discussed the effects of turbulent intensities and equivalence ratios. The effects of equivalence ratios on laminar HCNG-30 premixed flames were analyzed, and as the equivalence ratio decreased, the instability was dominated by both D-T instability and D-L instability. With the presence of turbulence, the flame structure became more wrinkled due to the turbulence effects and interactions with intrinsic instabilities. The influence of turbulence on the flame structure declined as the flame developed to a certain size.
