Opis:: The paper is concerned with an important issue from the field of thermoacoustics - the numerical modelling of the flow field in the thermoacoustic engine. The presented way of modelling is based on the solution to fundamental fluid mechanics equations that govern the flow of compressible, viscous, and heat-transferring gas. The paper presents the way of modelling the thermoacoustic engine, the way of conducting calculations and the results which illustrate the correctness of the selected computational technique.

Opis:: Thermoacoustics has become a promising technology to use heat from low temperature sources to drive engines. This study proposes a single-stage thermoacoustic travelling-wave engine for waste-heat recovery at 150°C. All the construction details of such a system are provided. A recently developed configuration of a looped tube with an impedance matching side-branch stub is proposed. A numerical model of the engine is built in DeltaEC software to conduct the simulations. Furthermore, a detailed thermodynamic analysis of the engine is presented, including an energy balance, a description of the basic acoustic parameters in a steady state, as well as a study of a variable load influence on the performance of the engine. The Authors pointed out the necessity of the engine optimization and a proper choice of load related acoustic impedance, which would consider a trade-off between high power and high efficiency. Eventually, a possibility of achieving 40% exergy efficiency of the proposed engine is confirmed.
