3. Design. The fundamental design is an enclosure, or cavity, into which there is a vent, or port. The dimensions of these two areas are critical in that combined they determine the resonant frequency of the resonator. The shape of the cavity itself has a function, in that a smooth round cavity has very little frictional loss.

Porous absorbers tend to be smaller in size and are easier to design and build, as well as less expensive overall than resonant absorbers. However, the deep bass attenuation of a porous absorber is generally inferior, so its usefulness for attenuating lower frequency room resonances is more limited. 1998-11-06 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.

performance, tunability and efficiency of membrane absorbers. The first approach uses a loudspeaker surround as the mounting for the membrane, increasing the moving mass, thereby lowering the resonant frequency of the system. Using a loudspeaker surround also allows for more accurate prediction of the absorber’s performance as the mounting

Thickness (mm) Mass (Kg/m 2) Resistance (Pa.s/m) Flow resistivity (Pa.s/m 2) Hole diameter Slot width (mm) Hole Slot spacing (mm) Layer 2. These tests led to a design of membrane absorber, and a small batch of prototypes was constructed and tested in a reverberation room.

Gas concentrations between 25-2010 ppmV were fed into the shell side of a membrane module whilst water-NaOH solutions flowed counter-currently in the fibre lumens. The possible integration of a membrane absorber system into existing odour treatment strategies was assessed by comparing the membrane system, based on the experimentally determined mass transfer coefficient, with existing full scale biofiltration plants.

DESIGN OF ABSORBER CHAPTER No.8 DESIGN OF ABSORBER 8.1 ABSORPTION The removal of one or more component from the mixture of gases by using a suitable solvent is second major operation of Chemical Engineering that based on mass transfer. In gas absorption a soluble vapors are more or less absorbed in the solvent from its mixture with inert gas.
