چکیده
|
Flame propagation in a closed pipe with diameter 0.1 m and 5.1 m long,as well as length to diameter ratio (l/d) of 51,was studied experimentally. hydrogen/air,acetylene/air and methane/air with stoichiometric concentration were used to observe the trend of flame propagation throughout the pipe. experimental work was carried out at operating condition: pressure 1 atm and temperature 273 k. results showed that all fuels are having a consistent trend of flame propagation in one-half of the total pipe length in which the acceleration is due to the piston-like effect. beyond the point,fuel reactivity and tulip phenomenon were considered to lead the flame being quenched and decrease the overpressures drastically. the maximum overpressure for all fuels are approximately 1.5,7,8.5 barg for methane,hydrogen,and acetylene indicating that acetylene explosion is more severe. © 2016 penerbit utm press. all rights reserved.
