摘要:
The linear acoustic propagation in rigid planar sharp bends and bifurcation ducts is analyzed using a Green’s‐function integral technique often known as the surface element method. The acoustic characteristics of the sharp bend differ substantially from those of a circular bend with identical turning angle, width, and centerline length. The acoustic loading resulting from a duct bifurcation is highly two dimensional beyond the first cutoff frequency.
