Abstract
Natural phenomena adhere to certain conservation laws that follow from fundamental symmetries in nature. We assume a simplified model for a free, round, fully developed turbulent jet in air and apply the conservation laws to this model to see what we can predict concerning the physical properties of such a jet. We compare these results to carefully conducted laser Doppler anemomenty (LDA) measurements in a fully developed turbulent round jet. We find that both first, second and third order statistical quantities are controlled by a single scaling factor—the downstream distance x.
