Experimental investigation of wall-pressure fluctuations on a fully appended submarine model at high Reynolds numbers
Peng Jiang, Haoyu Zhang, Yi Dai +3
This paper addresses a critical gap in hydroacoustics through a systematic wind tunnel investigation of wall-pressure fluctuations on the fully appended DARPA SUBOFF model at opera…
Experimental study on the wall-pressure fluctuations of flow over an axisymmetric hull
Peng Jiang, Haoyu Zhang, Yi Dai +3
Wall pressure fluctuations beneath the turbulent boundary layer of high-speed underwater vehicles are crucial for hydro-acoustics and acoustic stealth. However, a comprehensive und…
Effects of appendages on the turbulence and flow noise of a submarine model using high-order scheme
Peng Jiang, Shijun Liao, Ling Liu +1
This study employs high-fidelity numerical simulations to investigate the influence of appendages on the turbulent flow dynamics and far-field acoustic radiation of the SUBOFF subm…
Utility of High-Order Scheme for Unsteady Flow Simulations: Comparison with Second-Order Tool
