Study of Standing-Wave Thermoacoustic Electricity Generators for Low-Power Applications
This paper is concerned with the study of low-cost, low-power thermoacoustic electricity generators. Based on target electrical output power values of 50 and 100 W, three standing wave prototypes (of both one-stage and two-stage prototypes) integrating a

Physics-Based Statistical Learning in Thermoacoustics
Thermoacoustic oscillations arise because of the interaction between acoustic waves inside a duct or a combustion chamber, and heat release rate oscillations at the flame or heater location.

Adjoint Methods as Design Tools in Thermoacoustics
In a thermoacoustic system, such as a flame in a combustor, heat release oscillations couple with acoustic pressure oscillations. If the heat release is sufficiently in phase with the pressure, these oscillations can grow, sometimes with catastrophic ...

Mathematical aspects of thermoacoustics [PDF]
This thesis addresses the mathematical aspects of thermoacoustics, a subfield within physical acoustics that comprises all effects in which heat conduction and entropy variations of the gaseous medium play a role. We focus specifically on the theoretical
