English abstract:
In this contribution we discuss the simulation based design and application
of MPAs (micro-perforated absorbers with special emphasis on MPPs, microperforated
plates).Thereby, we present our Finite-Element (FE) framework based
on non-conforming grid techniques to allow e cient simulations of large HVAC
systems. The MPPs are modeled by an homogenization ansatz using the JCAL
(Johnson-Champoux-Allard-Lafarge) model based on Biot-theory. The contribution
is concluded by an investigation of the behavior of MPPs under flow conditions.
