Abstract

Attention is given to D(p)(r), the second-order pressure structure function in nominally isotropic turbulence. Using direct numerical simulation data for decaying isotropic turbulence, D(p)(r) is evaluated by a number of different methods. Calculations based on the joint Gaussian assumption are in closest agreement with the direct estimates of D(p). Dp was also calculated from longitudinal velocity fluctuation measurements in decaying grid turbulence.
