Transmission eigenvalues and thermoacoustic tomography [PDF]
, 2013 The spectrum of the interior transmission problem is related to the unique determination of the acoustic properties of a body in thermoacoustic imaging. Under a non-trapping hypothesis, we show that sparsity of the interior transmission spectrum implies ...

Using a side-branched volume to tune the acoustic field in a looped-tube travelling-wave thermoacoustic engine with a RC load [PDF]
, 2017 Travelling-wave thermoacoustic engine utilises a compact acoustic network to obtain a right time-phasing between the acoustic velocity and pressure oscillations within the regenerator to force gas parcels to experience a Stirling-like thermodynamic cycle.

Energy and AI, 2021 The intermittent nature of operation and unpredictable availability of renewable sources of energy (e.g., wind and solar) would require the combustors in fossil-fuel power plants, sharing the same grid, to operate with large turn-down ratios. This brings

Acoustic and Large Eddy Simulation studies of azimuthal modes in annular combustion chambers [PDF]
, 2012 The objectives of this paper are the description of azimuthal instability modes found in annular combus- tion chambers using two numerical tools: (1) Large Eddy Simulation (LES) methods and (2) acoustic solv- ers.

Numerical Investigation of the Wake Vortex‐Related Flow Mechanisms in Transonic Turbines
International Journal of Aerospace Engineering, Volume 2020, Issue 1, 2020., 2020 As the core equipment of the power generation system, a gas turbine is an indispensable energy‐converting device in the national industry. The flow inside a high‐pressure turbine (HPT) is highly unsteady, which has a great influence on the aerothermal performance and structural strength.
