Properties of large-scale methane/hydrogen jet fires

A mathematical model for flame volume estimation based on flame height of turbulent gaseous fuel jet

“…Here, it is noticed that, the relating of flame volume to jet parameters is implicitly reflected by flame height, which is dominated by the jet parameters such as source diameter and fuel supply rate (heat release rate) [24][25][26][27][28][29]. For example, Hu et al [24] have proposed a modified flame height correlation using flame Froude number given in [25].…”

A consideration of methods of determining the radiative characteristics of jet fires

“…This approach was adopted by Studer et al [10] to determine the fraction of heat radiated from hydrogen flames from experimental measurements taken by radiometers aligned with their normal perpendicular to the flame axis and approximately half-way along the flame axis and 0.5 radial distance.…”

The Correlation for Non-premixed Hydrogen Jet flame Length in Still Air

“…In 2009 Studer et al [16] published results of their experimental study on hydrogen jet fires. Hydrogen was stored in a 0.025 m 3 Type IV tank at 10 MPa and released horizontally through a 5 m long flexible pipe with internal diameter of 15 mm.…”

“…The pipe was mounted 1.5 m above the ground and the hydrogen was ignited immediately after release by an electric spark. Pressure and temperature were recorded in the pipe just prior to the nozzle but were not given in the publication [16]. The authors investigated releases through orifices of 4, 7 and 10 mm.…”

“…The jet flame length was measured for orifice diameter 1, 2 and 3 mm. The experimental set up was similar to [16] and there were some doubts about the accuracy of the mass flow rate provided. By this reason the experimental data on pressure and temperature were used in this study to calculate the mass flow rate and other flow parameters at the nozzle by use of the under-expanded jet theory [7].…”
