Sampling in thermoacoustic tomography [PDF]
Journal of Inverse and Ill-posed Problems, 2020 AbstractWe explore the effect of sampling rates when measuring data given byMffor special operatorsMarising in Thermoacoustic Tomography. We start with sampling requirements onMfgivenfsatisfying certain conditions. After this we discuss the resolution limit onfposed by the sampling rate ofMfwithout assuming any conditions on these sampling rates.

Thermoacoustic Soret separation
The Journal of the Acoustical Society of America, 2022 In a fluid mixture in a channel with an axial time-averaged temperature gradient, high-amplitude oscillating flow can greatly increase the axial flux of thermal diffusion (Soret) separation of the components of the mixture. The enhancement occurs when the oscillating lateral temperature gradient greatly exceeds the axial gradient, causing a large ...

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.

A numerical study of the relation between the acoustic generator geometry and the heat transfer conditions [PDF]
Archive of Mechanical Engineering, 2018 Modern gas turbine systems operate in temperatures ranging from 1200°C to even 1500°C, which creates bigger problems related to the blade material thermal strength.

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
