内容記述 | In the previous report, the cross-independence of the velocities at two points in homogeneous turbulence was employed as the closure hypothesis for the equations of the velocity distributions, and it was shown that there exists an inertial normal one-point velocity distribution. In the next report, the same hypothesis was applied to the equation for the two-point velocity distributions, but no solution was given due to the formal complexity of the equation. In this report, a closed equation is derived for the two-point velocity distributions using the same hypothesis in another meaningful way, and it is shown that again there exist inertial normal distributions for the velocity-sum and the lateral velocity-difference distributions. The longitudinal velocity-difference distribution is found to be inertial normal only outside the dissipative and inertial ranges and tends to the delta distribution in the limit of coincidence of the two points. | |||||
