Cross-sectional area variation as a key factor in pressure wave attenuation in bubbly flows: A theoretical analysis

Summary by Phys.org
Pressure waves propagating through bubble-containing liquids in tubes experience considerable attenuation. Researchers at the University of Tsukuba have derived an equation describing this phenomenon, demonstrating that beyond liquid viscosity and compressibility, variations in tube cross-sectional area contribute to wave attenuation.
