Mass-spring analyzes of thermal acoustic oscillations in a helium system.

Author(s) : GU Y., TIMMERHAUS K. D.

Summary

A mass-spring theory has been developed for predicting the frequency and pressure amplitude for thermal acoustic oscillations. There is relatively good agreement between the theoretical predictions and the experimental results. Additionally, the theory also predicts the stability characteristics for thermal acoustic oscillations by comparing the values of the viscous resistive coefficient and the driving force coefficient. Due to the relatively simple mathematics involved in this theory, these results can be determined rather quickly.
