| Abstract: | Based on Doppler Frequency-Shift Effect,three typical techniques as LDA,PDPA,PIV are reviewed and their applications in measuring flow fields in stirred vessels with one or multistage impellers are summarized.Validation of CFD(computational fluid dynamics) using LDA,PDPA,PIV data is also discussed and illustrated.Laser Doppler measurement techniques combining with CFD will be the powerful tools in optimization and design of stirred vessels in the future. |
