    摘要: Thermoacoustic sensors, such as dynamic pressure sensors, in the combustor measure vibratory responses of the combustor. An integrated monitoring and control system controller correlates sensor readings with combustion thermoacoustic properties in order to identify combustion anomalies by wavelet or Fourier analysis techniques; determine bulk temperature characteristics within the combustor with dominant mode frequency analysis techniques; and optionally determines absolute active path temperatures within the combustor with acoustic pyrometry transmission and time-of-flight analysis techniques. In some embodiments all of the monitoring functions are performed with a commonly shared array of thermoacoustic sensors that function as both combustion dynamics thermoacoustic vibration/wave receivers and acoustic transmitters. The monitored combustion properties are used for controlling gas turbine combustion.

    摘要: A nuclear thermoacoustic device includes a housing defining an interior chamber and a portion of nuclear fuel disposed in the interior chamber. A stack is disposed in the interior chamber and has a hot end and a cold end. The stack is spaced from the portion of nuclear fuel with the hot end directed toward the portion of nuclear fuel. The stack and portion of nuclear fuel are positioned such that an acoustic standing wave is produced in the interior chamber. A frequency of the acoustic standing wave depends on a temperature in the interior chamber.

    摘要: Continuous casting moulds used in automated installations casting metal melts into strands require comprehensive, reliable real-time monitoring. Currently used systems are susceptible to damage and limited to just a few sensors, as arrangements involving a higher number of sensors have proven impractical due to the substantial effort they cause when exchanging a mould. To overcome this obstacle it is suggested to use wirelessly interrogable passive surface acoustic wave (SAW) sensors for monitoring of physical parameters in continuous casting moulds, and install at least one wireless link section in the signal path between SAW sensors and their reader devices. Continuous casting moulds thus become easily exchangeable with their sensors installed, making it industrially practicable to equip continuous casting moulds with a significantly higher number of sensors than previously feasible.
