Title
Comparison Of Measured Velocity Structure Functions And Energy Dissipation Theories In Turbulent Flows
Abstract
Structure functions of turbulent velocity fluctuations up to the eighteenth order were measured on the axis of a modified air jet at Reynolds numbers Rλ = 72 and Rλ = 102, using parallel hot-wire sensors. Measured values were compared with those predicted by the log-normal, β-model and a new theory based on gamma statistics for the local average dissipation rate. The data from this experiment and several earlier experiments agree more closely with the predictions of the gamma model rather than those of the log-normal model.
