see the book of Peric & Ferziger

so can we say that the position of uu and ww is in pressure nodes and uw's is in velocity nodes? (in 2DV)

homogeneous correlations uu and ww are each one in the same staggered position of the respective velocity componente, without interpolation, while u and w are in different positions and you must interpolate to compute uw. However, if you want all the Reynolds tensor computed in the pressure location you must interpolate all components...
