At low Mach numbers, they are the sole source of aeroacoustic (*) sound.
The growth of these objects ceases in the Kutta condition. Hemholtz developed a series of theorems summarizing the properties of three dimensional ones. At low Mach numbers, they are the sole source of aeroacoustic (*) sound. A staggered row of these structures named after von Karman develop in the oscillating wake behind a cylinder when the Reynolds number exceeds 40. For 10 points, name these fluid regions that are not present in potential flow and are characterized by a high concentration of vorticity.
