Thermo-Fluid Mechanic Study of Thermoacoustic Devices

摘要

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.
