A simulated study on intermittent flame feature of mass fire in channel structure
Case Studies in Thermal Engineering, 2022 Compared with the intermittent thermal-flame behavior in ordinary building, the flame behavior may also occur in mass fire inside channel structures, accompanied by distinct thermal characteristics, which is rarely studied.

Dynamic behavior and flame acceleration of outwardly expanding flame in hydrogen-air mixture
Nihon Kikai Gakkai ronbunshu, 2016 From the perspective of safety, it is necessary to assess the risk of hydrogen-air deflagration accurately. Especially, flame propagation velocity is one of the most important factors.

Flame Characteristics of Group Fires
Fire Science and Technology, 2004 In this paper, simulating a group fire in a densely inhabited area with weak small wooden buildings, we performed reduced scale model experiments to investigate flame merging. To study this phenomenon, a lot of experiments were performed using crib and liquid fuel.

Impact of the Flame-Holder Heat-Transfer Characteristics on the Onset of Combustion Instability [PDF]
, 2013 In this article, we investigate the impact of heat transfer between the flame and the flame-holder on the dynamic stability characteristics of a 50-kW backward-facing step combustor. We conducted a series of tests where two backward step blocks were used,

Advanced Engineering Materials, EarlyView.New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...
