Abstract

Researchers from MGSU (Moscow) revealed the effect of an adjacent room to the pressure of the gas explosion in a room that has a window. They found that the explosion pressure in this case is significantly (2.5-fold) higher than the pressure of the explosion in a room without an adjacent room. This result confirms the studies Molkov V. V., they spent a little earlier. Review of foreign publications shows that the priority of the study of this effect remains for Russian scientists. We confirmed this effect also experimentally, but studies have been conducted in more detail. In the experiment we used a model installation dimensions 0.5x0.5x1.0 m on the long side is divided into two chambers, one of the chambers had the stroke window of 0.15x0.15 m, and the partition between the chambers was a passage of the same size. The first chamber is filled with propane. Control and measurement has been computerized, he worked on the original program. Data processing was carried out in an environment Microsoft Excel. Experimentally it was found that the greatest effect is seen when ignited gas-air mixture in the area located between the center of the room and closer to the window (maximum excess-more than three times). Directly by the window effect is weaker (1.8 times) and virtually non-existent when ignited in a region close to the passage connecting room and the adjoining room.
