Summary: This paper presents a systematic investigation on the jet fire in a pit, including the variations of gas entrainment mode and flame behavior. A dimensionless heat release rate coupling the pit geometrical property is developed to correlate the flame area and length, which is validated by experimental data. Models for predicting the thermal radiation of the jet fire are proposed.

Summary: This paper systematically investigates jet fire in a pit (JFP) caused by the explosion of underground pipelines. The study observes different types of flames and develops correlations for flame length and width in various pits, as well as proposes models to predict thermal radiation. The research indicates that flame buoyancy becomes more significant than nozzle exit momentum as the nozzle exit velocity increases, leading to the evolution of JFP behavior.

Summary: In this work, the characteristics of cryogenic hydrogen fires were investigated experimentally, including flame size, radiative power, and flame temperature. The results showed that flame size was influenced by nozzle diameter, stagnation pressure, and temperature. A correlation model was proposed for predicting flame size at different temperatures.

Summary: This work investigates the flame geometrical characteristics of vertical downward turbulent jet fires in still air. The study proposes a new physical model and conducts CFD simulation to show the combustion structure. The research reveals the inner flow field and average mixture fraction of a downward jet fire and validates the CFD result with experimental data. It also discusses the differences between downward, upward, and horizontal jet fires and presents a physical model considering the initial downward momentum, flame buoyancy, and air entrainment.

Summary: This paper focuses on the risk analysis of hydrogen transmission in existing pipelines, comparing the individual risk associated with hydrogen jet fires with natural gas. The analysis shows that hydrogen jet fires yield lower lethality levels and decrease faster with distance than natural gas jet fires, leading to significant lower individual risk in large pipelines. However, ignition effects dominate the individual risk for decreasing pipeline diameters, causing increased individual risk in the vicinity of the pipeline compared to natural gas.

Summary: A new facility was used to model the jet flame ejected from the ruptured tank, and the geometrical features of the flame and radiant heat fluxes on the tank surface were measured. Two thermal radiation models were established to predict the radiant heat flux field. The prediction of the models agreed well with the experimental measurements.

Summary: This study experimentally investigated the flame extension below the ceiling induced by two unequal square gaseous fires in a 1:10 scale tunnel. The flame length and tilt angle were analyzed based on the measured gas temperatures. A new model for flame length and a merging criterion were proposed. The results provide useful references for personal evacuation, fire rescue, and risk assessment in tunnels.

Summary: This study focuses on the burning behaviors of horizontal hydrogen jet fires under the action of a water curtain system. The experimental results show that the shape of the hydrogen jet flame expanded on the water curtain is elliptical at different conditions. A new dimensionless heat release rate is proposed to estimate the flame extension length.

Summary: Hydrogen has gained attention worldwide for its zero pollution and recycling potential, but its flammability range and low ignition energy can pose safety problems such as hydrogen jet fire. To explore methods of preventing hydrogen jet fire, experiments were conducted to study flame behavior under the influence of nitrogen and carbon dioxide jets as fire extinguishing agents. Results showed that decreasing the installation height of the extinguishing agent nozzle led to an increase in the reduction ratio of vertical flame length, indicating the potential extinguishing effect when the agent is injected at the root of the hydrogen jet flame. Additionally, the thermal radiant flux and total heat flux received by the flame were analyzed, as well as the extinguishing limits of hydrogen jet flame under the effects of nitrogen and carbon dioxide jets.

Summary: This paper investigates the flame evolution characteristics and radiation behavior of low-momentum jet flames affected by cross airflow. The results show that the flame length increases at first and then decreases with the increase of cross airflow, and the flame's inclined angle gradually increases while its width decreases. The study proposes a model for predicting the radiation distribution considering cross airflow velocity and jet velocity. It is found that the radiation flux downstream of the fire source initially increases and then decreases with the gradual increase in cross airflow velocity. A model of flame radiation fraction considering cross airflow velocity and jet momentum is also developed. These findings provide valuable insights for the design of safer gas storage and transportation facilities.

Summary: This paper investigated the flame extension characteristics and temperature distribution of a methane jet diffusion flame with hydrogen addition. A physical and mathematical model was derived to predict the flame extension area. Machine learning methods were also used to estimate the gas leakage flow rate from temperature data. The results demonstrate the potential for industrial combustion systems and fire safety engineering applications.

Summary: The effects of adding hydrogen to methane were investigated through the transition from laminar to turbulent regimes in non-premixed lifted flames. The lift-off heights varied depending on fuel tube diameter, jet velocity, and hydrogen ratio. The study discussed transitional phenomena and proposed an improved relationship between lift-off heights and fuel jet velocities. The blow-off mechanism and overall stabilization modes of the flames were also explained.

Summary: This paper presents an experimental investigation on the interaction of double turbulent jet flames with different spacings. It is found that flame buoyancy, exit momentum, and nozzle spacing significantly affect the flame merging behavior. A new dimensionless parameter is proposed to describe the merging probability of double jet flames dominated by flame buoyancy and exit momentum. A correlation is developed to predict the mean flame height of double jet fires.
