Acoustic scattering by one bubble before 1950: Spitzer, Willis, and Division 6.

Area of Science:

• Fluid dynamics
• Acoustics
• Wave propagation

Background:

• Acoustic scattering by single bubbles is fundamental to modeling bubbly liquids.
• Early research in the 1940s is largely found in inaccessible wartime reports.

Purpose of the Study:

• To provide a coherent summary of acoustic scattering by single bubbles.
• To synthesize findings from previously unpublished wartime reports.

Main Methods:

• Literature review and synthesis of historical reports.
• Analysis of acoustic scattering phenomena.

Main Results:

• Consolidation of key findings on single bubble acoustic scattering.
• Identification of crucial parameters influencing scattering behavior.

Conclusions:

• The paper offers a unified perspective on historical acoustic scattering research.
• Enhanced understanding of bubbly liquid dynamics is facilitated by this summary.
