  author={Cheng‐Hsiung Kuo and Da Wei Yang},
This experimental investigation reveals the lock-on phenomena of cavity flows under periodic excitations. All the experiments were conducted in a recirculating water channel. The LDV system and the laser-light sheet technique are employed to perform the quantitative velocity measurements and the qualitative flow visualization, respectively. The Reynolds number, based on the momentum thickness at the upstream edge of the cavity, is kept around 152. An oscillating flat plate, situated above the… CONTINUE READING
