摘要

In the present work, the structure-based model (SBM) was evaluated in a turbulent flow in a cylindrical pipe rotating around its longitudinal axis. It was found that the SBM is able to predict the flow accurately at various Reynolds numbers and under stronger rotation than what is possible with the Reynolds stress transport models (RSTMs). In a fully developed pipe flow, the SBM, being a linear model, slightly improves the profiles obtained with the non-linear RSTM (Speziale et al., 2000). However, like the RSTMs do, the SBM significantly overpredicts the turbulent kinetic energy level in this part of flow in comparison with the results of experiments.
