The triple velocity correlation and the pressure-velocity correlation, whichplay an important role in the transport equation for Reynolds stress, are evaluatedwith the aid of a shear-turbulence theory. The theory is based on the Direct-Interaction (propagator-renormalization) formalism incorporated with theseparation of space and time scales between the mean and fluctuating fields. Asa consequence, these correlations are shown to be expressed by the use of twostatistical quantities of the fluctuating field, say, the turbulent energy and theenergy dissipation rate (or the size of largest eddies). Results obtained are ap-plicable to the estimate of turbulence transport models.
