Abstract

Physical parameters as indicators for detonation regularity have been previously identified; however, a metric for the degree of regularity has yet to be defined. Quantifying the degree of regularity in cellular detonations offers valuable insight into their stability and potential failure. An experimentally derived regularity parameter, the coefficient of variation of velocity ((σ/μ)V/DCJ), is defined. This regularity parameter forms the finite boundaries relative to the effective activation energy using statistically significant and temporally resolved experiments.

爆轰规律的量化
作为爆轰规律指标的物理参数先前已被确定;然而,衡量这种规律性程度的标准尚未确定。对细胞爆炸的规律性程度进行量化,可以对其稳定性和潜在的失败提供有价值的见解。定义了一个由实验导出的正则性参数——速度变化系数((σ/μ)V/DCJ)。这个规则参数形成了相对于有效活化能的有限边界,使用统计意义和时间分辨实验。

期刊介绍: The mission of the journal is to publish high quality work from experimental, theoretical, and computational investigations on the fundamentals of combustion phenomena and closely allied matters. While submissions in all pertinent areas are welcomed, past and recent focus of the journal has been on: Development and validation of reaction kinetics, reduction of reaction mechanisms and modeling of combustion systems, including: Conventional, alternative and surrogate fuels; Pollutants; Particulate and aerosol formation and abatement; Heterogeneous processes. Experimental, theoretical, and computational studies of laminar and turbulent combustion phenomena, including: Premixed and non-premixed flames; Ignition and extinction phenomena; Flame propagation; Flame structure; Instabilities and swirl; Flame spread; Multi-phase reactants. Advances in diagnostic and computational methods in combustion, including: Measurement and simulation of scalar and vector properties; Novel techniques; State-of-the art applications. Fundamental investigations of combustion technologies and systems, including: Internal combustion engines; Gas turbines; Small- and large-scale stationary combustion and power generation; Catalytic combustion; Combustion synthesis; Combustion under extreme conditions; New concepts.
