“…For example, the characteristics of burner dimensions, external heat losses and effect of wall conductivity in meso-scale burners were employed using FLUENT software [17]. Recent numerical works has also given new ideas of blowout limits in different condition like in high pressure conditions [1], in preheating channels [23] and on the planar combustors [4]. Concerning the dimension of numerical simulation, two-dimensional (2-D) numerical simulation is unable to present the conductive heat transfer from a flame holder to the outer wall of combustor.…”

Micro power generation system is a field of study that has come into interest by many researchers due to the strong demands for low weight and long-life power sources of electronic devices. These has led to the increasement of meso and micro-scale combustion investigations. In order to fully understand more on this field of study, a numerical stimulation is utilized to investigate the effect of heat recirculation on the blowout limit for micro combustion. Four different combination of tube combustors is used to investigate their blowout limit such as quartz-brass tube combustion combination for unburned-burned region of micro combustor tube. The combination of tube combustors is then investigated using three-dimensional (3D) numerical simulation. The results suggested that by utilizing brass tube on either region of unburned or burned tube is able to improve the value of heat conducted on inner wall of via inner wall of the tube greatly. Due to the conductivity of brass tube is much larger than quartz tube, the improvement is expected.

“…Rucheng Liu studied the gas explosion problem for a full-size roadway using FLACS and determined the propagation rules for the flames, shock waves and dynamic pressure for different roadway structures (Liu and Zhu 2018). Ma and Cai studied a gas explosion by experiment system, and determined the distributions of the pressure field and temperature field after an explosion (Cai et al 2019;Ma et al 2019). However, at present, few studies have been conducted on the damage to ventilation facilities caused by a gas explosion, and how the failure of the ventilation system would expand the impact of the disaster, which could provide important support for the rapid recovery of normal ventilation after an accident.…”
