| Abstract: | Vortex shedding and aeroacoustic interaction in flow around flat bodies is an important field that grabbed researchers' attention. Industrial applications of this flow include axial flow compressors, finned heat exchangers, and ducting systems. Aeroacoustic coupling in such systems affects their performance and structural fatigue. Building a solid understanding of flow regimes and predicting the occurrence of aeroacoustic resonance is crucial for avoiding excessive acoustic vibrations and reducing undesirable noise. This paper presents a review of various studies to gain an understanding of the identification of flow regimes, principles of aeroacoustic coupling, and prediction of aeroacoustic resonance in flow around single and two flat plates in tandem. The paper also highlights the research gaps in these areas. The review found that while the understanding of flow regimes around single flat plates is well-established, significant research gaps remain in identifying flow regimes in flow around two flat plates. In addition, a research gap exists in predicting aeroacoustic resonance as both numerical and experimental approaches have some limitations, particularly in the accurate prediction of resonant flow velocities and the accounting for deviations in Strouhal numbers values.
