带流动的亥姆霍兹共振器：导入流体流动的 CGNS 数据
Application ID: 143941
Helmholtz resonators are used in exhaust systems, as they can attenuate a specific narrow frequency band. The presence of a flow in the system alters the acoustic properties of the resonator and the transmission loss of the subsystem. In this tutorial model, a Helmholtz resonator is located as a side branch to a main duct. The transmission loss through the main duct is investigated when a flow is introduced.
In this model the mean flow is imported and mapped using the Imported Fluid Flow interface and the CFD Data (CGNS) function. The model is set up for the case where the Mach number is equal 0.1. The acoustics problem is then solved using the Linearized Navier-Stokes, Frequency Domain (LNS) interface.
