N2 - Results are presented for a single-laser Krypton Tagging Velocimetry (KTV) scheme applied to the flow over a hollow cylinder in a shock tube. This scheme is comparatively simpler and cheaper to implement than previous dual-laser schemes and maintained an SNR of ≈ 2 in these experiments. Results are presented for experiments performed in 99% N2/1% Kr and 75% N2/5% Kr/20% O2 with Reynolds numbers ranging from 1e5-1e6. For the first time KTV is implemented in air at a pressure of 19 kPa and in N2 at 25 kPa. The data points over the cylinder are mapped to corresponding wall-normal locations above a flat plate, which allows for comparison with flat-plate boundary-layer theory. Agreement between theory and experiment is excellent, bringing confidence to the utility of KTV in impulse facilities and at the aforementioned conditions.
