Entire Flow

A model and procedure for calculating turbulent mixing of a confined jet is presented. The flow consists of a high velocity jet which is directed into a constant diameter duct, where it mixes with a concentric, low velocity stream. The flow model which includes the wall boundary layer covers the entire flow development from the mixing tube entrance to the start of fully developed flow conditions. The calculated results are presented for a range of flow conditions and are compared with the experimental results of a previous paper by the same authors. It was found that including the boundary layer, as part of the model, gave results which were significantly different and in better agreement with experiment for small and moderate velocity ratios.

Acceptable Measure

An accurate measurement of the average stagnation pressure at a duct cross section is necessary when trying to determine the loss characteristics of low-pressure loss components such as power plant ducts and electrostatic precipitators. In these components, the pressure loss is usually of the same order of magnitude as the gas velocity head. This paper describes how to calculate average stagnation pressure for flows with nonuniform velocity profiles. Guidelines are presented on the techniques needed to achieve an acceptable measure of the average stagnation pressure. These guidelines were developed for use by power plant engineers and experimental flow-model investigators. The required mathematical techniques, a computer program, and some experimental model results are presented.
