Abstract
The study of an external heat input motor utilizing the thermoacoustic effect is a hot topic in the field of energy and efficiency improvement. With the increasing need for energy conservation and sustainable development, this approach offers prospects for a more efficient conversion of heat into mechanical energy. The aim of this study is to investigate and optimize a thermoacoustic effect motor to improve its efficiency. The work includes theoretical and experimental studies, selection of the optimal working substance, and development of heat exchange elements, optimization of the working cycle and investigation of new materials. Despite the need for further research and development, these technologies have the potential for large-scale application, contributing to reducing dependence on traditional energy sources and reducing the negative impact on the environment.
