摘要
Results of experimental and numerical investigations of air flows over a two-dimensional backward-facing step are presented. The lengths of separation and reattachment on the upper and lower walls were measured nonintrusively using closely spaced, multi-element hot-film sensor arrays for Re less than or equal to 3000 and expansion ratios of 1.17 and 2.0. The hot-film sensor measurements are in good agreement with the present as well as previous numerical predictions. It is anticipated that this measurement capability will provide a practical means for the study of unsteady flow phenomena with flow separation as well. (C) 1998 Academic Press.
