Summary

 
Object and purpose of research.This research studies an engine with external heat input as per Stirling cycle. The purpose of this study was to develop a harmonization method for external heating circuit parameters, taking into account efficiency, specific power and environmental requirements.
Subject matter and methodsThis work is based on the methods of complex systems theory, classic thermodynamics and heat & mass exchange.
Main results.This study formulated current challenges in improving the external circuit efficiency for Stirling engine, e.g. increase of temperature in the combustion space, increase of temperature for heat exchange surfaces of the heater and making the temperature in the external circuit more uniform; efficiency increase and size reduction of the heater, application of indirect heating systems in the heater, formulation of non-uniform heating problem in thin thick-walled heater tubes.
Conclusion.Obtained results make it possible to formulate simulation problems for the working processes in the combustion space with varying arrangement of separate elements, taking into account specified boundary conditions for the combustion chamber of Stirling engine.
