A novel membrane sound absorber based on the magnetorheological membrane (MRM) is developed for active sound absorption. Due to its good flexibility and stretch-ability, the MRM consisting of carbonyl iron particles (CIPs) and polydimethylsiloxane elastomer matrix can be easily deformed. The deformation of MRM is investigated by the digital image correlation method.
In this paper, we investigate a parameter analysis of a nonlinear membrane absorber based on TET technique to design the NES. The physical parameters of the membrane and the place of the membrane on the wall of the cavity are studied.
av A Bologna · 2020 — Here we show that this problem can be addressed by a proper design of the to external temperature variations, since the vacuum between the absorber and the membrane distillation and waste heat recovery from portable generator sets. Compact cylinders without piston rod with membrane and a much shorter stroke than Rodless diaphragm drive: design consists of two metal plates with rolled in rubber bellows or hose. 60 mm; Max. energy absorption per stroke 0.005 . Influence of gas sparging on membrane performance Co-current Absorption of Ammonia in Water to Design an Innovative Bubble Plate Absorber. av K Eriksson · 2015 · Citerat av 2 — Abstract. This thesis treats the design and characterization of amplifiers operating up to Membrane Technology”, IEEE Transactions on Microwave Theory and will act as an absorber that reduces the magnitude of the substrate modes [81].
•Hög styvhet och hårdhet. •Mycket låg fuktabsorption. •God beständighet mot krypning. •Låg glidfriktion och glidslitage. Membrane absorbers, also known as panel and diaphragmatic absorbers, utilize the resonant properties of a membrane to absorb sound over a narrow frequency range. Engineers typically employ unperforated, limp panels of wood, pressed wood fibers, plastic or other rigid or semi-rigid materials when constructing membrane absorbers. A hollow fibre (HF) polypropylene membrane gas absorber was investigated for the removal of hydrogen sulphide (H2S) from gas streams.
