Information

Acoustics equations

The Acoustics example is a system of three equations

where p is the gas pressure, v its velocity, phi the concentration of the contaminant and K₀, rho₀, v₀ are constant values. The eigenvalues

where c₀ is a constant value, and the eigenvector matrix

are given explicitly in this example. In general, the user must compute the eigenvector matrix and eigenvalues by using other Modelica packages.
