Biography

Cindy Rakowski is a Research Engineer in the Hydrology Group. She is a member of a team of engineers and scientists that focuses on the development and application of computational fluid dynamics to solve problems in environmental and engineered systems.

Ms. Rakowski provides technical expertise in the areas of structured and unstructured mesh generation, flow simulations in 1-, 2-, and 3D. This broad knowledge has led to the development of innovative methodologies for applying computational fluid dynamics (CFD) to rivers and their engineered structures. She is experienced using Gridgen (Pointwise, Inc.) several CFD solver codes including Star-CD (ADAPCO), and MASS1 and MASS2 (PNNL codes); GIS software (Arc/Info (ESRI), and visualization tools such as Tecplot (Amtec).

Research Interests

Integration of diverse data sources into a GIS framework to facilitate analysis, and map production that shows results in an easy-to-understand manner.
Application of numerical flow models to problems of biological significance, with management applications.
