CFD for Turbomachinery What to Expect and What Not to Expect

This paper presents a high-level overview of computational fluid dynamics (CFD) methods, with a focus on turbomachinery. It describes the advantages and limitations of CFD, to show when CFD is or is not an appropriate tool to answer a question. It also covers how to use different CFD methods to approach different kinds of problem most efficiently. The paper emphasizes practical CFD, showing how to get the information needed with the minimum time and money. The material is intended for new CFD analysts and for those who work with CFD analysts and need to understand their results without being CFD practitioners themselves.
