Abstract
- ObjectiveThis study focuses on the quasi-static pressure characteristics of a confined cabin in a water mist environment. MethodsFirst, on the basis of the theoretical model of quasi-static pressure in a confined cabin in adiabatic ideal gas, two new assumptions are added to establish a theoretical model of quasi-static pressure in a confined cabin in a water mist environment. Internal explosion experiments in a confined cabin with and without water mist are then performed with the charge as an independent variable, and the quasi-static pressure is measured and used to verify the mitigation effect of water mist on quasi-static pressure and obtain its empirical formula.Results Combined with the theoretical model and experimental data analysis, it is concluded that the ability of water mist to reduce quasi-static pressure increases with the increase in charge-volume ratio, but the increase rate gradually decreases. Both the theoretical formulas of the afterburning correction term and empirical formulas can be used to estimate the quasi-static pressure peak in the cabin.ConclusionsThe experimental results verify the mitigation effect of water mist on quasi-static pressure. The experimental data of this paper and others shows good agreement with the empirical formula of the quasi-static pressure peak of an internal explosion in a water mist environment, and can be used to estimate the quasi-static pressure peak.
