Thermo-Fluid Mechanic Study of Thermoacoustic Devices

Abstract

The research described is articulated in three parts: a) Development and study of a quasi-one-dimensional, time-domain, non-linear, simplified model of a thermoacoustic device. b) Multidimensional numerical modeling based on low-Mach-number asymptotics. c) Visualization of high-speed oscillating temperature fields in a thermoacoustic stack by means of holographic interferometry combined with high-speed cinematography.
