水雾环境下密闭舱室内爆准静态压力特性试验研究
Experimental investigation of quasi-static pressure characteristics of the confined cabin in the water mist environment
摘要
Abstract
[Objective]This study focuses on the quasi-static pressure characteristics of a confined cabin in a water mist environment.[Methods]First,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 ana-lysis,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 afterburn-ing correction term and empirical formulas can be used to estimate the quasi-static pressure peak in the cabin.[Conclusions]The experimental results verify the mitigation effect of water mist on quasi-static pres-sure.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.关键词
