Аннотация

The effect of various levels of initial turbulence on the decay of the velocity fluctuations in convergent channels with different contraction ratios has been experimentally investigated. The results of the experiments indicate that the level of turbulence has a strong influence on the longitudinal velocity fluctuations and a weaker effect on the transverse fluctuations. The experimental data demonstrate the inapplicability of the rapid distortion theory and the need for that theory to take into account the energy dissipation, the integral scale and the degree of anisotropy.
