论文摘要
从构成统计平面，湍流的预热火焰的等温线的集合开始，从质量流量的整体配方开始，对相应的湍流火焰速度的缩放是在不调用damk {Ö} hler的假设的情况下得出的。使用较大的Karlovitz数，Unity Lewis编号，直接数值模拟（DNS）数据集对N-Heptane/Air混合物的数据集进行了验证，该数据集得到了验证。引入了一个新的长度尺度，以量化预混合火焰结构内等温线的波动距离。
Starting with an integral formulation of mass flow rate through an ensemble of isotherms constituting a statistically planar, turbulent premixed flame, a scaling for the corresponding turbulent flame speed is derived without invoking Damk{ö}hler's hypotheses. Major approximations and interim results are validated using a large Karlovitz number, unity Lewis number, Direct Numerical Simulation (DNS) dataset of n-heptane/air mixture, computed with reduced chemistry. A new length scale quantifying the fluctuation distance of the isotherms within the premixed flame structure is introduced.
