Reynolds decomposition

Short definition of Reynolds decomposition
Decomposition of a time series of a measured parameter into time mean and fluctuating components

This is the common definition for Reynolds decomposition, but other definitions maybe discussed within the wiki.

In progress: Decomposition of a time series of a measured parameter such as temperature and velocity components into time mean and fluctuating components. The deviation from the mean can be further decomposed into waves and turbulent fluctuations.
