Abstract

This investigation comparing wind tunnel results and pretest and posttest CFD predictions was undertaken as part of the NATO AVT-183 task group, which was established for the purpose of assessing the reliable prediction of separation onset for flows through experimental and computational means. Experimental data sets include forces and moments, steady and unsteady surface pressure measurements, flow-field velocity measurements using PIV, and measurements to quantify the test section environment and uncertainties. Comparisons and evaluations of Technische Universität München (TUM) wind tunnel results and pretest and posttest CFD predictions using OVERFLOW2 and HPCMP CREATE™-AV Kestrel are presented. Kestrel steady-state and unsteady Spalart-Allmaras DDES results provided very good agreement to test PIV measurements and wing surface CP for most cases.
