Evaluating the onset conditions of a thermoacoustic Stirling engine loaded with an audio loudspeaker

open access: yesFrontiers in Thermal Engineering, 2023
This paper aims to evaluate the onset conditions of a thermoacoustic Stirling engine loaded with a commercially available audio loudspeaker. The thermoacoustic engine converts supplied heat power into mechanical power in the form of sound, without any ...

Sampling in thermoacoustic tomography [PDF]

open access: yesJournal 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

open access: yesThe 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 ...

Inverse problems in thermoacoustics

open access: yes, 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 ...

Experimental Investigation on the Thermoacoustic Effect in Easily Accessible Porous Materials

open access: yesEnergies, 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]

open access: yesArchive 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]

open access: yesRoyal 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
