This report documents a numerical modeling study conducted to assess the pressure environment and relative biological performance of the existing turbine runner design at the U.S. Army Corps of Engineers (USACE) McNary Dam to establish a baseline for comparison to planned replacement runner designs. Computational fluid dynamics (CFD) models of the turbine unit constructed for this study were analyzed using a streamtrace-based technique called the Biological Performance Assessment (BioPA), which was developed at the Pacific Northwest National Laboratory (PNNL).
