The analysis of the process tending towards equilibrium in transitional and turbulent wall flows
Journal Title: INCAS BULLETIN - Year 2010, Vol 2, Issue 2
Abstract
Starting from the integro-differential formulation (IDF) [1], [2] of the basic conservation equations in wall flows, the authors perform a qualitative analysis of the microscopic-macroscopic domain. According to IDF, the kinetical energy presents a mean distribution and a lot of similar terms called FLUONS. Their various combinations lead to physical fluctuations and their dynamical equilibrium concerns the existence of an associated distribution of the kinetical energy, which is a solution of IDF. The global contributions of the fluctuations are, therefore, estimated as analytical formulae for the wall flows. The experiments confirm these results.
