| Title of the article | Areas of damage during emergency on the gas pipeline |
| Abstract. | Problem statement. Main gas pipelines are classified as energetically stressed objects. With the increase in their service life, there is a need to model an emergency breaks and analyze the distribution of the damaging factors of the accident. In the article, the emergency rupture was simulated for a section of a high pressure gas pipeline and a test problem was numerically solved, which allows calculating the pressure at the rupture point, the discharge height, and the possible gas zone depending on the diameter of the gas pipeline and the pumping mode. Results. A numerical experiment was conducted on a stationary outflow of gas – methane from a high pressure gas pipeline. The dependences of the distribution of the total pressure and velocity along the axis of the gas ejection are obtained. The zone of possible toxic effects on humans and animals, as well as the boundary of the zone of potential thermal effects, provided that there are external sources of ignition, are determined. Conclusions. The significance of the results obtained for the construction industry lies in the fact that, knowing the parameters of free jet gas outflow during a possible emergency depressurization of the gas pipeline, it is possible to calculate the gas zone by the known methods, which increases the safety of residential buildings during the design of gas pipelines. Keywords: gas pipeline, emergency depressurization, discharge height, numerical simulation, gas zone. |
