密闭直管内瓦斯爆炸温度和压力的实验研究
Experimental Study on Gas Explosion Temperature and Pressure in Closed Straight Tube
摘要
Abstract
Gas explosion is an instantaneous process. In order to analyze the rule of explosion pressure and temperature change during gas explosion, the gas explosion experiment with the volume fraction of 6. 5% -10. 0% was carried out by using a closed straight tube gas explosion experiment system. The results show that when the gas volume fraction is 9. 5%, the explosion temperature reaches 1292. 27 K in the tube and the explosion pressure attains 0. 766 MPa;mean while the time required to these highest temperature and maximum explosion overpressure shortens to the least, 351 ms and 208ms respectively. Temperature near the ignition source is the highest, and that at the end of the pipeline is the lowest.关键词
