Abstract
Some publications describe an effect, produced during a physical model experiment, when an adjacent gas-free room influences the gas explosion pressure in a room with a window. The explosion pressure in this case significantly exceeds (2.5 times) the explosion pressure in a room without an adjacent room. This result has been confirmed by our studies. Based on other available information about the influence of the ignition point location on the explosion pressure in one room, it was suggested that this could be true for an explosion in two rooms. In our studies we used a test unit with two connected chambers, each having a volume of 1.125 m 3 . It turned out that this influence of the adjacent volume was not so unambiguous as it was described in those publications. It was found out that the maximum effect of explosion pressure amplification by the adjacent room is achieved, when the igniter is located in the chamber filled with a gas-air mixture in the area between the center of the chamber and the window (maximum amplification by more than 3 times). This effect is lower directly by the window (1.8 times) and is practically absent in case of ignition within the area near the passage connecting the chamber with the adjacent room. This suggests that the effect discovered earlier is a special case of the general dependence of the gas explosion pressure in two chambers on the igniter location.
Highlights
IntroductionThe idea of the influence of an adjacent gas-free room, connected to the base room, on the gas explosion development was clearly shaped for the first time in works of researchers from the Moscow State University of Civil Engineering [1]
Much attention has been paid to a gas explosion in a single room with a window
To summarize the research results, we can review the dependence of the maximum explosion pressures on the igniter's location in two cases: first – in the single chamber, second – in the chamber connected with the adjacent chamber
Summary
The idea of the influence of an adjacent gas-free room, connected to the base room, on the gas explosion development was clearly shaped for the first time in works of researchers from the Moscow State University of Civil Engineering [1]. They showed that contrary to expectations the adjacent room serves not an explosion damper, but an explosion amplifier in case of an explosion in the base room. As for the certainty of the gas explosion pressure amplification effect in a room connected with an adjacent room, where only the air is present, we have recently published materials [2] confirming the experiment results
