“…Many studies have been carried out to investigate combustion characteristics of HENG, including the combustion rate, the concentration limits of flame propagation, and the ignition delay. 84,87,89,138 The Wobbe index is defined as the ratio of the high heating value of the gas to the square root of its relative density. This will directly affect the heat input to the gas appliance and is often used to evaluate gas interchangeability.…”

Natural gas-hydrogen hybrid combustion retrofit method and practice for F-class heavy-duty combustion engines

“…The catalytic detector required more frequent calibration (every three months) than the infrared detector. CFD analysis of the ventilation in the combustion engine hood was performed as a means of determining the required change in location and number of gas detectors [17], and three additional detectors were added for the detection of gas leaks in the hood as a means of maintaining a safe level of gas detection.…”

Structure Optimization of Hydrogen‐Fueled Multiple Direct‐Injection Trapped Vortex Combustor Using Response Surface Method

“…Sharifzadeh et al [ 13 ] performed large eddy simulation of swirling flow in a TVC, the results show that the cavity recirculation zone has a positive effect on the turbulence flow field, including a larger central recirculation zone, higher turbulence intensity, and smoother strain rate. Du et al [ 14 ] experimentally researched the combustion characteristics of swirling flow in a single trapped vortex combustor, the results show that the combustor has high performances on the total pressure recovery, combustion stabilization, combustion efficiency, and outlet temperature distribution. Wang et al [ 15 ] experimentally investigated the effect of cavity size on the ethylene combustion process, it can be found that vortex appears under all working conditions, but the lean ignition and blowoff limits do not vary monotonically with the cavity size, and the flame intensity in larger cavity is weaker than that in smaller cavity.…”
