Inner cutoff scale of flame surface wrinkling in turbulent premixed flames

摘要: The inner cutoff represents the smallest scale for interaction of turbulent eddies with premixed flame front. nondimensional has been shown to Karlovitz number, Kaβ, where β is −12. Three experimental data sets, available statistical information, strongly agree this scaling. However, five two without error statistic, seem favor = −13, in accordance direct numerical simulation results. expressions reported literature, obtained through data, or physical reasoning, have evaluated by comparing sets recently. It that Gibson scale, which was proposed as and asserts an inverse square dependence on does not show any agreement
