Теоретичне обґрунтування методу проектування корабельних отворів з застосуванням системи підпору повітря на основі струменевого водогазового апарату
To theoretically substantiate the method of designing ship apertures with the use of a local air suppression system, the paper considers the solution of a planar two-dimensional hydrodynamic problem of operation ofa jet water-gas apparatus (JWGA) in a semi-bounded volume during a fire. The mechanism of distribution of the velocity fields of the air-gas medium at the open side cutoff is elaborated. Its dependence on the parameters and operating characteristics of the JWGA, as well as on the initial characteristics of the ejected gas-air medium are established.
