Since the experimental values obtained for the second order structure function only deviate slightly from the 2 / 3 value predicted by Kolmogorov theory, the value for p is very near to 5 / 3 (differences are about 2% [30]).

[1] [2] The expected value, u ¯ {\displaystyle {\overline {u}}} , is often found from an ensemble average which is an average taken over multiple experiments under identical conditions. The expected value is also sometime denoted u {\displaystyle \langle u\rangle } , but it is also seen often with the over-bar notation.
The first published English grammar was a Pamphlet for Grammar of 1586, written by William Bullokar with the stated goal of demonstrating that English was just as rule-based as Latin. Bullokar's grammar was faithfully modeled on William Lily's Latin grammar, Rudimenta Grammatices (1534), used in English schools at that time, having been ...
In physics, the Landau–Hopf theory of turbulence, named for Lev Landau and Eberhard Hopf, was until the mid-1970s, [clarification needed] the accepted theory of how a fluid flow becomes turbulent. It states that as a fluid flows faster, it develops more Fourier modes .

2) It is the most general of all turbulence models and works reasonably well for a large number of engineering flows. 3) It requires only the initial and/or boundary conditions to be supplied. 4) Since the production terms need not be modeled, it can selectively damp the stresses due to buoyancy , curvature effects etc.
