The structure of average turbulent flow field
Open Physics, 2010 Abstract A mathematical formalism to reflect the turbulent hierarchic eddy structure in an average turbulence description is discussed. The formalism is founded on simultaneous application of turbulent flow field splitting procedures by the motion variability and by the motion order explained in the paper. It is shown that this formalism
