Abstract

Chaos and unpredictability in some classical dynamic systems are eliminated by referring the governing equation to a specially selected rapidly oscillating (non-inertial) frame of reference in which the stabilization effect is caused by inertia forces. The resulting motion is found as a sum of smooth and non-smooth (rapidly oscillating) parts. The solution is stable and reproducible in the sense that small changes in initial conditions lead to small changes in both smooth and non-smooth components. In this interpretation, conceptually the closure problem in turbulence is reduced to the problem of finding such a frame of reference where the high Reynolds number instability is eliminated. The usefulness of the approach is illustrated by examples.
