Acoustic absorption and generation in ducts of smoothly varying area sustaining a mean flow and a mean temperature gradient

Autor: Yeddula, Saikumar Reddy, Gaudron, Renaud, Morgans, Aimee S.

Publikováno v: Journal of Sound and Vibration, 116437 (2021)

In ducts with varying cross-sectional area and sustaining a subsonic non-isentropic mean flow, the axially varying flow conditions affect the acoustic energy balance of the system. This is significant in understanding and controlling thermo-acoustic

Analytical models for thermoacoustic interactions in axially varying flows

Autor: Yeddula, Saikumar Reddy

Thermoacoustic instabilities are a major problem in boilers, low NO_x gas-turbine combustors, and rocket engine combustors. They occur due to positive feedback between the unsteady heat release of the combustion and the acoustic waves, which leads to
