also illustrates the importance of detailed analysis and post-processing of simulated results. Not only for turbulent flows but also for any complex flow-modeling problem, before one uses simulated results, systematic error analysis based on numerical experiments as well as some experimental validation is essential. Examples of the validation of single-phase flows generated by different impellers are discussed in Chapter 10.
