A Reynolds stress model for near-wall regions of low Reynolds numbers proposed by the author in a previous paper is, with some modifications of the model function and model constant, applied to an accelerated turbulent boundary layer. The predicted case is a relaminarizing flow presented at the 1980-81 Stanford conference on Complex Turbulent Flows. Comparison of the numerical results with the experimental data includes profiles of the mean velocity and streamwise turbulence intensity at several stations as well as the streamwise variations of the momentum thickness, the shape factor and the skin-friction coefficient. it is shown that the predictions are generally in close agreement with the experimental data including the profile of streamwise turbulence intensity which is not predicted directly by the two-equation models.
