2008 ULTRASONIC BENCHMARK STUDIES OF INTERFACE CURVATURE—A SUMMARY

In the 2008 QNDE ultrasonic benchmark session researchers from five different institutions around the world examined the influence that the curvature of a cylindrical fluid‐solid interface has on the measured NDE immersion pulse‐echo response of a flat‐bottom hole (FBH) reflector. This was a repeat of a study conducted in the 2007 benchmark to try to determine the sources of differences seen in 2007 between model‐based predictions and experiments. Here, we will summarize the results obtained in 2008 and analyze the model‐based results and the experiments.
