This chapter describes the physics interfaces found under the
Aeroacoustics branch
.
The aeroacoustic branch has physics interfaces to solve the fully linearized acoustic equation for several physical conditions, they are: the linearized Euler (LE) equations, the
linearized Navier–Stokes (LNS) equations, and the
linearized potential flow (LPF)
equations. These equations are also referred to as convected acoustics.
