Abstract
A Reynolds stress model for near-wall and low-Reynolds-number regions is extended to adverse pressure gradient conditions. In the development of the model, the generation and diffusion terms in the transport equation for the turbulence energy dissipation rate and a model function for viscosity-dependent regions are recasted by examining a typical failure of prediction. The development of turbulent boundary layer in a strong adverse pressure gradient in an experiment by Samuel and Joubert is numerically predicted with the model. The predictions are compared extensively with the experimental data including th turbulence intensities in three directions. It is shown that the predictions are generally in good agreement with the experiment.
