Results of experimental research into correlations between hazardous factors of ignition of materials in premises

Abstract: Представлені результати експериментального дослідження динаміки небезпечних факторів стану середовища в моделюючей камері, а також їх автокореляцій і парних кореляцій при різних лагах для спирту, паперу, деревини і текстилю. Встановлено, що інформативною ознакою раннього виявлення загорянь є ступінь взаємної кореляції флуктуацій факторів при нульовому лагу. Виявлено, що для розглянутих матеріалів ознакою раннього виявлення їх загоряння є коефіцієнт парної кореляції СО і температури при нульовому лагу, що має д… Show more

“…In this case, fluctuations of hazardous factors of the gaseous medium are not considered. Article [9] explores temporal autocorrelations and paired correlations of hazardous factors of the gaseous medium in the region of a near-ceiling jet, simulated in a special chamber. However, correlations of fluctuations of dynamics of hazardous factors of the gaseous medium, which are essential for detection of early ignitions, are not studied.…”

“…In this regard, it is necessary to use modern frequency-temporal representations, specifically the methods of frequency-temporal distribution, for analysis of a subtle structure of early ignition factors at premises [12,13]. The research into dynamics of major actual [14,15] and model hazardous fires [9] indicate that ignitions violate equilibrium state of the gaseous medium in premises. Ignitions also result in random fluctuations of the basic parameters of the gaseous medium, localized in space and time.…”

“…Techniques for preventing man-made emergencies due to fire based on increments in the state of the gas environment in the premises are not considered. The study of temporary covariance and mutual covariance of the main parameters of the state of the gaseous medium during fires in the room model was performed in [21]. It is noted that for detecting the onset of a fire in the premises, the current changes in the parameters of the state of the gaseous medium, rather than their average value, are more important.…”
