2. Benchmark solution#
2.1. Calculation method used for the reference solution#
No reference solutions. The values tested for non-regression are those obtained with version 3.02.17.
2.2. Benchmark results#
Power spectral density of the pressure at the node at the right end of the tube, at frequencies \(\mathrm{10,}\mathrm{12,}\mathrm{14,}\mathrm{36,}\mathrm{38,}40\mathrm{Hz}\). These frequencies are close to the two natural frequencies taken into account (\(12.38\) and \(37.36\mathrm{Hz}\)).
