title = "Experimental investigations on gas explosions by different ignition positions and solid obstacles in a partially confined region",
abstract = "The experimental studies have been performed to assess the effects of different ignition locations and wall obstructions in a partially confined rig, 235 mm in height, with a 1000 × 950 mm2 cross section and with a large top-venting of area of 1000 × 320 mm2. Four different ignition positions, at the bottom, side, corner and top, and three wall obstacles with blockage ratios ranging from about 10 to 30 \% were used. The comparisons between wall obstacles in the chamber showed that the dependence of overpressure on obstacle geometries and block ratios were quiet different compared with published experiments with a large L/D ratio enclosure. It was found that the smallest wall obstacle caused the highest overpressures while the largest one resulted in the lowest overpressures within the chamber. It was also found that the bottom ignition produced more flame surface area with corresponding higher overpressures than other ignition positions. The flame propagation and pressure development was highly dependent on the ignition source positions.",
