Membrane vibrating

Because the membrane vibrates in a compressional mode, rather than shear as in the TSM device, this sensor is most likely to be useful in a gaseous rather than liquid ambient. A gravimetric sensitivity, Sm. of 555 cm g has been reported [83] for one of these 1 GHz devices this value is in good agreement with what one would predict from the analysis cited in Section 3.5.2 below. [Pg.140]

Vibratory mechanism was one more interesting technique for reducing fouling negative effect. Vibrations can be apphed to flat sheet membrane modules, but many researchers tested the technique on performance of hollow fibers for different separation processes [3, 136]. One example of construction is shown in Fig. 9.10 [136] to assess the effect of axial membrane vibrations on mass transfer in a hollow fiber oxygenator. [Pg.427]

In the membrane process, however, pressurized operation does not cause mixing of anolyte and catholyte due to the dense structure of the membrane, and various advantages such as reduced operating voltage and membrane vibration can be gained by pressurizing both chlorine gas and hydrogen gas (77). [Pg.393]

Air bubbles can be introduced in a microfluidic mixer in order to enhance the mixing process. The surface of an air bubble in a liquid medium exposed to a sound field can act as a vibrating membrane. The membrane vibration causes a bulk fluid movement at the air-hquid interface. This effect, known as cavitation microstreaming, has been applied in microfluidic micromixers using a single bubble [181] (Fig. 19) or an array of bubbles [178, 179]. [Pg.56]

The purpose ofthe pressure wave simulations (the previously described moving membrane simulations) was to determine if molecular dynamics would allow the coherent transfer of mechanical energy across a fluid. In these simulations, if energy transmission is to occur, the membrane vibrational periods must be commensurate with the length ofthe nanotube and speed of transmission. [Pg.173]

Typical results are shown in Fig. 3, for which the bottom membrane vibrates with an amplitude of 0.5 A and a period of 1 ps. An amplitude of 0.5 A was chosen because at larger amplitudes, the fluid temperature built up, usually within 50 ps, to several thousand degrees. The top (driven) membrane, which has a mass of 40 amu and a fundamental vibrational period of 1 ps, shows no coherent motion even after 100 oscillations of the driving membrane. Other simulations, in which the period ofvibration was up to 5 ps and the mass ofthe driven membrane up to 100 amu, yielded virtually identical looking results. [Pg.173]

The previously described TFF products require a pump to produce crossflow along the membrane surface to generate the shear rate necessary to reduce polarization and fouling. In contrast, in this configuration, the membrane vibrates creating shear at its surface. This vibrating membrane arrangement. [Pg.409]
