SummaryThe possibility of obtaining two-dimensional turbulent jet flow from a series of closely-spaced uniform holes in line has been investigated both theoretically and experimentally. The case studied was that of a jet discharging into still fluid of similar density at incompressible speeds. Such a quasi-two-dimensional jet is a particular example of a multiple-interfering jet group.

Similarity Relationships

The mean-velocity profiles and entrainment rates in the similarity region of a two-dimensional jet are generated by a simple superposition of Rankine vortices arranged to represent a vortex street. The spacings between the vortex centres, their two-dimensional offsets from the centreline, as well as the core radii and circulation strengths, are all governed by similarity relationships and based upon experimental data.Major details of the mean flow field such as the axial and lateral mean-velocity components and the magnitude of the Reynolds stress are properly determined by the model. The sign of the Reynolds stress is, however, not properly predicted.

Flow Through

A theory was developed to predict the signal and noise, in terms of stagnation pressures, at the entrance to a blocked rectangular receiver placed in an otherwise free two-dimensional turbulent jet. Experimental verification of the theory was then undertaken. The results showed that a reversal of flow takes place within the entrance of a blocked receiver, so that stagnation conditions do not exist at the entrance and, hence, the theory is not valid under these conditions. The theory was easily altered to predict the momentum flux through a receiver which presents very little resistance to flow through its passageway. Employing a device called a momentum meter the altered theory was verified. The main results of this work are: (a) The noise-to-signal ratio of a receiver held fixed in the jet is minimized by keeping the receiver near the centerline of the jet. (b) The ratio of noise to change in signal, with relative movement between the jet and receiver, is minimized by keeping the receiver away from the centerline of the power jet.
