EFFECT OF CONTRACTION ON A HOMOGENEOUS TURBULENT SHEAR FLOW.

Research output: Contribution to journalArticle

Abstract

A homogeneous turbulent shear flow in its asymptotic stage of development was subjected to an additional (longitudinal) strain by passing the flow through gradual contraction in the direction perpendicular to that of the mean shear. Two contractions, of area ratio 1. 4 and 2. 6, were used. The mean velocity distributions agree quite well with calculations based on the (inviscid) Bernoulli equation. Until at least half-way down the contraction with the larger area ratio, the rapid-distortion calculations considering only the streamwise acceleration were found to be reasonably successful in predicting the turbulent intensities. For the smaller-area-ratio contraction, corrections for the 'natural development' of the shear flow become important nearly everywhere. Refs.
