Similarity and Decay Laws of Momentumless Wakes.

Abstract

The decay laws of momentumless wakes as predicted by different models are investigated. Existing work is critically reviewed, and the models are compared with themselves and with experiments. Subsequently, the decay of momentumless wakes is examined using the Reynolds stress models of Lauder, Reece and Rodi, as well as a simpler turbulent energy-dissipation (K-epsilon) model. The last model is shown to be better than the more sophisticated former ones, and exhibits generally fair agreement with existing data. (Author)
