Hi,all if I know all the velocity information(including mean velocity, fluctuation velocity and instataneous velocity) of a turbulence filed. How can I compute the two-point correlation of the fluctuation velocity?(In other words, How to compute the correlation of fluctuation velcoity in different location of the same time).

Can any of you give me some references or some formula? Thanks!!
