The first paper in this section, Pressure Effects on Triple Correlations in Turbulent Convective Flows, by André, Lacarrère, and Traoré, considers the rate equations for velocity /scalar triple correlations in a purely convective turbulent flow. In particular, following a general discussion of the effect of pressure on the triple correlations, the triple correlations involving the pressure gradient are broken into a combination of rapid and relaxation terms (expressed as suitable groups of triple correlations) similar to the combinations that are customary in the second order equations, with unknown constants. Only situations in which transport is negligible are considered. The equations are solved to compare with laboratory data on unsteady thermal turbulent convection, the unknown constants being evaluated by optimization. Finally, sensitivity studies are carried out on the constants.
