Compression wave gas dynamics
WebJan 3, 2024 · 1.1 Propagation of Sound. Sound waves are the weakest pressure waves. When sound waves propagate through a quiescent gas, the gas particles oscillate around a fixed location. A sound wave is characterized by its amplitude and frequency spectra. Moreover, sound waves are not accompanied by flow, which is the movement of the … WebThe problem of the passage of acoustic waves in the neighborhood of a gas bubble in a tube is formulated and solved numerically. The main parameters determining the bubble …
