G. S. Jones,C. Barbi,D. P. Telionist conditions, it is admissable to identify actual behavior with some reasonably well-fitting probabilistic description of it. What the authors call the confusion problem arises where such admissibility is implicitly assumed. Some examples of this problem are discussed, viz. those accruing from the d

A Review of Unsteady Turbulent Boundary-Layer Experimentslow facilities are described, and the related unsteady turbulent boundary- layer experiments are cataloged and discussed. The measurements that have been obtained in the various experiments are described, and a complete list of experimental results is presented. All the experiments that measured ins

Dynamic Behavior of an Unsteady Turbulent Boundary Layergion, the boundary layer sees a linearly decreasing free-stream velocity. This velocity gradient oscillates in time, at frequencies ranging from zero to approximately the bursting frequency. Considerable detail is reported for a low-amplitude case, and preliminary results are given for a higher ampl

Periodic Turbulent Pipe Flow at ‘High’ Frequencies of Oscillationcture of unsteady turbulent flows. First, experimental data obtained in a very simple unsteady flow namely periodic turbulent flow in a long circular pipe are presented. Secondly, a calculation procedure based on an existing one-equation steady flow turbulence model has been developed and used to pr

Turbulence Modulated by a Coherent Shear Wave in a Wall Boundary Layernd constitute a dynamic equilibrium. The general aim of our investigations is to study this system by introducing small external perturbations and observing the resulting time-dependent departure from the equilibrium. The coherent shear wave used as perturbation throughout our experiments may either

Experimental Study of Two- and Three-Dimensional Boundary Layer Separationn the circular cylinder the steady and unsteady surface pressures and shear stresses are measured in order to investigate the separation of a quasi two-dimensional, oscillating boundary layer. The boundary layer separation occurring on the inclined prolate spheroid is examined by means of similar ex
