Frequency tuning algorithm for loudspeaker driven thermoacoustic refrigerator optimization

Abstract

Article describes the experimental method of acoustic pressure amplitude-frequency response measurement in resonator of thermoacoustic refrigerator with electromechanical generator of acoustic oscillations. Based on the results obtained the nonlinear mathematical model of thermoacoustic refrigerator with electromechanical generator is synthesized using the statistical methods of construction and evaluation of pairwise dependencies. The resonance frequency identification algorithm for thermoacoustic system parametric optimization is developed using the obtained mathematical model. Experimental verification of the proposed resonance frequency identification algorithm is considered. © 2012 Springer-Verlag.
