Figure 2.24: Multi-phase model vs. full flume single phase model illustrating velocity distribution across trough section for 6 inch water depth 2.3.8. Comparison with Laboratory Data Particle Image Velocimetry (PIV) and Acoustic Doppler Velocimetry (ADV) are two methods used to capture the velocity data from laboratory experiments. Acoustic Doppler Velocimeters are capable of reporting accurate values of water velocity in three directions even in low flow conditions. The main objective of the PIV tests is to obtain a 3-dimensional high-resolution velocity distribution, which is convenient for visual comparisons with CFD results. Comparisions of the CFD data with laboratory data for 6 inch and 9 inch water depths have been done. The agreement levels between multi-phase model results and experimental results for 6 inch water depth are depicted in Figure 2.25 and Figure 2.26. Since neither the PIV nor ADV can capture the data for the whole section, the corresponding data ranges are framed out in CFD results respectively. TRACC/TFHRC Y1Q3 Page 34
