Figure 5 shows that the ratio of the flows has no significant effect on the driving force for sensible heat recovery. This insignificant influence m11ayofb1e5 related to the relatively low moisture supply by the "exhaust" air, which can be removed efficiently by the "fresh" air with the ...
A constant high voltage and driving electric signal are applied between the membrane and back plate and they force the membrane to vibrate. Such transducer possesses a quite wide bandwidth but usually operate in the frequency range higher than a few hundreds of kHz [34–36]. In addition, they...

Circumferential Excitation According to the excitation principle, two force loads are added sequentially to two adjacent zones with equal axial length of /4, where is the wavelength. The two loads have the same time duration, but with a time shift of T0/4 one after the other, where T0 is ...
