Mine exogenous fire is the main disaster in coal mines. Owing to complicated structure and ventilation network, smoke movement control branched roadway fires of mines more than that traffic tunnel fires. In this study, backlayering length critical velocity a for occurred branch were studied with varying locations. The results suggest from does not spread along width centerline roadway, but forms an early "snake-shaped" structure. variation dimensionless variable ln(Q˙*1/3/V*) divided into...
Accurate and rapid measurement of ventilation resistance is crucial for achieving effective real-time airflow control in underground systems. Conventional methodologies are frequently constrained by operational inefficiency substantial inaccuracies. To overcome these limitations, this study proposes an innovative approach employing fractal theory to quantify roadway surface roughness determine parameters. The characterization utilizes two descriptors: dimension (D) scale parameter (C)....
Following a fire incident in coal mine dead-end roadway, shutting down the local ventilator can influence progression. This study delves into impact of shutdown time (i.e. air supply cessation time) on source combustion dynamics through small-scale experiments. Results indicate that sudden will prompt ghosting flame and even self-extinguishing. The emerges due to uneven distribution fuel vapor oxygen concentrations, its moving direction is related ventilation conditions mode. And burning...
In this study, smoke movement characteristics and temperature in the blind roadway connected main were mainly investigated numerically. The outcomings indicate that as fire source gradually moves away from heading face, flame tilts face to portal of roadway. gas downstream during ventilation is higher than situation without ventilation, it depends only on location. high-temperature will generate energy loss passed through bifurcation structure, resulting a sudden decline longitudinal...
The cooling fan is one of the important noise sources for new energy vehicles, and research on its aerodynamic aeroacoustic characteristics great help to improve noise, vibration harshness performance vehicles. However, most these studies focus impeller, little consideration has been given study shroud. Based coupling calculation method large eddy simulation Ffowcs-Williams Hawkings acoustics model, in a with shroud are investigated at flow rates from 0.623 kg/s 1.019 (where 0.865 rate...
The development of high-performance sensors is great significance for the control volatile organic compounds (VOCs) pollution and their potential hazard. In this paper, high crystalline V2O5 nanoparticles were successfully synthesized by a simple hydrothermal method. structure morphology prepared characterized TEM XRD, cataluminescence (CTL) sensing performance was also investigated. Experiments found that as-prepared not only shows sensitive CTL response good selectivity to 2-butanone, but...
