论文摘要

除NS方程本身外,已经提出了Navier-Stokes流体的固定状态。 NS进化与可逆性之间尤其等效。自然要测试是否假设混乱的假设可以将波动定理应用于可逆流。这里提供了一个示例,这也导致可能在不可逆地发展的系统中测试波动定理的预测。

Stationary states of Navier-Stokes fluids have been proposed to be described equivalently by several alternative equations, besides the NS equation itself. In particular equivalence between the NS evolution and a reversible. It is natural to test whether, assuming the Chaotic Hypothesis, the Fluctuation Theorem can be applied to the reversible flows. Here an example is provided which also leads to the possibility of testing the prediction of the fluctuation theorem even in systems evolving irreversibly.
