The two combining sites between the cylinder and the transducer locate at the adjacent wave loops of bending vibration of the transducer and have a distance that equal to the half wave length of bending standing wave excited in the cylinder.
The results indicate that, in the two standing waves, the vibration amplitudes of wave loops are inconsistent.
Previous simulation results have proved that, in the two standing waves, the vibration amplitudes of wave loops are inconsistent.
Two mean values of vibration amplitudes of wave loops were taken to represent two standing waves, and results indicate that they are very close to each other.
The company's micro-wave loop - the special equipment used for cross-country telecasting (Coaxial cable is old hat now) was set up three weeks before the hearings began.
Compared with the conventional thermoacoustic heat engine which involves a traveling-wave loop and a long resonator, it has advantages of compact size and potentially high thermal efficiency.
Compared with the conventional thermoacoustic heat engine which involves a travelling-wave loop and a resonator, it has advantages of compact size and potentially high thermal efficiency.
In the configuration, three identical thermoacoustic heat engine units are evenly incorporated in a closed traveling-wave loop, in which three pulse tube cryocoolers are connected to the branch of each thermoacoustic heat engine.
The latter will be automatically analysed as previously described,and principal component analysis ratio, total cosine R-to-T, TWM dispersion, normalized T-wave loop area, T-wave loop dispersion, and relative T-wave residuum will be computed.
