Scale Covariance of the Wrinkling Law of Turbulent Propagating Interfaces

Abstract

The physical process governing turbulent propagating interfaces is determined experimentally in scale space by analyzing the interface geometry and using the Kolmogorov cascade. Its scale covariance is evidenced for any scale range and any interface geometry, either Euclidean, fractal, or inbetween. This reveals a similarity of geometry formation more extended and more essential than the similarity of geometry itself.
