The dynamic behavior and disintegration mechanisms of a fan liquid sheet in a quiescent
atmosphere are investigated over a broad range of differential injection pressures up to Δ
p≈ 70 bar through experiments, proper orthogonal decomposition (POD) and spectral
analyses, and linear stability analysis (LSA). By fan liquid sheet, we mean a diverging and
attenuating liquid stream emanating from a flat fan nozzle with high velocity. High
spatiotemporal resolution backlit images reveal the formation-growth-fragmentation process …
