Thermoacoustic instability is defined as the excitation of acoustic modes in chambers with heat sources due to the coupling between acoustic perturbations and unsteady heat addition. The major objective of this paper is to achieve accurate theoretical results in a thermoacoustic heat transfer process. We carry out a detailed heat transfer analysis…

Thermoacoustic instability can appear in any thermal device when the unsteady heat transfer is favourably coupled with the fluctuations of acoustic pressure. In this paper, we present a project type of physical measuring and modelling task; the aim of our project is to help our students increase their knowledge of thermoacoustics. Our paper…

Thermoacoustic instability plays an important role in various technical applications, for instance in jet or rocket motors, thermoacoustic engines, pulse combustors and industrial burners. The main objective of this paper is to present the theory of thermoacoustic oscillations, and for this purpose a Rijke-type thermal device was built. The Rijke…

In this article we present a project that includes physical measuring, examination and modelling task. The main objective of this article is to present the theory of thermoacoustic oscillations; for this purpose, a simple Rijke-type thermal device was built. The Rijke tube is essentially a pipe open at both ends with a mean flow and a concentrated…

In this article we present project work on physical measurements and an examination task with a Rijke tube. The aim of our project is to help students increase their knowledge of thermoacoustics while at the same time developing their applied information technology skills and improving their cooperation skills. Our school project promotes pedagogy…
