Abstract: | A comparative assessment is presented of three different versions of high-Re k- models of turbulence for simulation of the flow past the entire length of axisymmetric bodies: standard, Chen and Kim-modified, and RNG-derived versions. Comparisons show that the standard model with wall functions can predict the flow characteristics at least as accurately as the other two. Application of the low-Re Lam and Bremhorst model further improves the predictive capability of wall-related quantities by removing the need for wall functions. |
