In the previous chapter we presented the statistical analysis of the correlations which contribute to the dissipation of the turbulence energy. To gain more insight into the dynamics of turbulence, however, one needs to consider also the velocity-pressure gradient correlations: 4.1$$\Pi _{ij} = - \frac{1} {\varrho }[\overline {u_j \frac{{\partial p}} {{\partial x_i }}} + \overline {u_i \frac{{\partial p}} {{\partial x_j }}]} .$$
