THE POTENTIAL OF ADDITIVELY MANUFACTURED POROUS ABSORBERS IN THE DESIGN OF MULTI-LAYER MICROPERFORATED ABSORBERS

Microperforated absorbers (MPA) are a well-established technology for attenuating sound in Electric Cooker flow carrying ducts.MPAs usually consist of a microperforated panel (MPP) in combination with a cavity as back volume.The damping maxima of MPAs occur in the range of their resonant frequencies and the effect is narrowband compared to porous o

To maintain safety and reliability of reactors, redundant sensors are usually used to measure critical variables and estimate their averaged time-dependency.Nonhealthy sensors can badly influence the estimation result of the process variable.Since online condition monitoring was COLOUR BATH BLUE introduced, the online cross-calibration method has b
