Inverse problems in thermoacoustics [PDF]
, 2021 Thermoacoustics is a branch of fluid mechanics, and is as such governed by the conservation laws of mass, momentum, energy and species. While computational fluid dynamics (CFD) has entered the design process of many applications in fluid mechanics, its ...

Weakly nonlinear thermoacoustics for stacks with slowly varying pore cross-sections [PDF]
, 2009 A general theory of thermoacoustics is derived for arbitrary stack pores. Previous theoretical treatments of porous media are extended by considering arbitrarily shaped pores with the only restriction that the pore cross-sections vary slowly in the ...

Experimental Investigation on the Thermoacoustic Effect in Easily Accessible Porous Materials
Energies, 2020 Thermoacoustic devices are the systems which use acoustic power to transport heat through a stack in a resonance tube. The stack is one of the most important parts of the thermoacoustic systems.

Experiments and modelling of rate-dependent transition delay in a stochastic subcritical bifurcation [PDF]
Royal Society Open Science, 2018 Complex systems exhibiting critical transitions when one of their governing parameters varies are ubiquitous in nature and in engineering applications. Despite a vast literature focusing on this topic, there are few studies dealing with the effect of the

Adjoint Methods as Design Tools in Thermoacoustics [PDF]
, 2019 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 ...
