On the comparison of LES data-driven reduced order approaches for hydroacoustic analysis

•Large eddy simulation coupled with modified Ffowcs Williams and Hawkings analogy.•Modal analysis via dynamic mode decomposition and proper orthogonal decomposition.•Reconstruction sensitivity towards SVD truncation was globally and locally measured.•DMD and POD with interpolation were utilized for interrogating intermediate snapshots.•Predictive character of each ROM was examined on spectral and acoustic performance.
