On the Two-Dimensional Mixing Region.
Abstract
An experimental investigation of the two-dimensional incompressible mixing layer was carried-out. The measurements provide new information on the development of the mean and turbulent fields towards a self-preserving state and on the higher-order statistical characteristics of the turbulent field. The revelance of initial conditions on the development of the flow is discussed in view of both present and previous data. Measurements of spectra, probability densities and moments to eigth order of all three velocity component fluctuations at various transverse position across the flow were carried-out using an on-line digital data acquisition system. The probability density distributions of the derivative and the derivative squared of the longitudinal and lateral velocity fluctuations were also determined. (Modified author abstract)
