Microprocessor System for Thermoacoustic Plants Efficiency Analysis Based on a Two-Sensor Method

The article is devoted to the dependency analysis of the thermoacoustic devices performance from acoustic wave parameters (frequency, pressure magnitude etc.). Detailed study of electroacoustic parameters impact on the overall productivity of loudspeaker driven thermoacoustic systems is given. Authors proposed the structure and algorithm basis of the microprocessor system for automated electroacoustic performance calculation. Proposed by Fusco et al. [1] two sensor method is implemented in digital signal processing algorithm for real-time acoustic power calculation. Synthesized microprocessor system is tested during the experimental research of the loudspeaker driven standing wave thermoacoustic refrigerator performance measurements. Analysis of the results obtained shows that the proposed microprocessor system with implemented data processing algorithm can be used for calculations of the thermoacoustic devices overall efficiency.
