초록
밀폐공간 내에 블록을 조합하여 부피와 표면적이 다르게 내용물을 채우고 용기 부피에 대한 내용물의 부피와 내용물의 표면적을 변화시키면서 LPG 또는 NG와 공기 혼합가스의 폭발특성을 측정하여 밀폐공간 내부에 있는 내용물의 부피와 표면적의 변화가 폭발특성에 미치는 영향을 해석하고자 하였다. 폭발용기는 가로 세로 높이가 각각
Variation of explosion characteristics by the blocks in closed vessel was investigated to analyse the effect of the block volume(volume blockage) and the surface area of the blocks(ratio of block surface area to vessel volume). Volume and surface area of blocks in explosion vessel were changed by the combination of blocks. The volume of explosion vessels was 270 liter, and the LPG-air or NG-air mixtures were ignited by the electric spark. Explosion pressure was measured with the strain type pressure transducer. From the experimental results, explosion pressure was decreased by the increase of the volume blockage and the block surface area. And the decrease of explosion pressure was more affected by the volume blockage than the surface area.
