本文研究了湍流燃烧中两种模型中小尺度随机平流的影响。假设速度场解相关足够快,我们(i)确定的前相对于平流的大小的波动的顺序;和(ii)表征他们的解决方案的哈密尔顿-雅可比方程迫使白色噪声。在最简单的情况下,结果产生,为两个模型,前布朗波动的规模相同的平流的大小。鉴于两个模型之间的已知差异,两个模型的波动相同有点令人惊讶。
We study the effect of small random advection in two models in turbulent combustion. Assuming that the velocity field decorrelates sufficiently fast, we (i) identify the order of the fluctuations of the front with respect to the size of the advection; and (ii) characterize them by the solution of a Hamilton–Jacobi equation forced by white noise. In the simplest case, the result yields, for both models, a front with Brownian fluctuations of the same scale as the size of the advection. That the fluctuations are the same for both models is somewhat surprising, in view of known differences between the two models.
