Computer Implementation of Arnott's Formulation of Thermoacoustics Using MATLAB

摘要

This thesis describes a Matlab computer program that implements Arnott'sformulation of thermoacoustics W.P. Arnott , et al, General formulation of thermoacoustics for stacks having arbitrarily shaped pore cross sections , J. Acoustic. Soc. Am. 90 (6), 3228-3237 (1991). The program calculates the resonance frequency and quality factor of a thermoacoustic prime mover below onset of self-oscillation. The results of this analysis are compared to measured values for both a closed end and an open end prime mover and to predictions of a standing wave analysis of prime movers A.A Atchley, Standing wave analysis of a thermoacoustic prime mover below onset of self-oscillation, J. Acoustic. Soc. Am. 92(5), 2907-2914 (1992). Prime mover, Thermoacoustics.
