Article Synopsis
- Flow-induced noise affects submarines' stealth, and understanding it for full-scale models has been challenging despite previous studies on smaller versions.
- The research team used simulations and advanced models to analyze flow noise, considering factors like Mach and Reynolds numbers, and developed a formula to establish a similarity law for sound production in submarines.
- Key findings include the minimal effect of attachments on noise similarity, the relationship of noise frequency to the Helmholtz number, and the ability to estimate full-scale flow noise based on small-scale models using the new similarity law.
