Meeting of the Center for Innovations and High Technologies

• December 11, 2023

The report entitled “Thermal Efficiency Analysis of Regenerative Thermodynamic Cycles” was delivered by Professor Nodar Kevkhishvili, the head of the Scientific Center for High-Temperature Thermophysical Processes at the Technical University of Georgia.  The speaker noted that one of the promising areas in solving environmental and energy problems can be considered the development and implementation of energy conversion systems based on regenerative cycle heat engines. Among the large number of regenerative thermodynamic cycles, several can be identified that have the highest thermal efficiency, equal to the action coefficient of the ideal Carnot cycle. Such highly effective cycles include the Stirling and Erickson cycles. As the speaker noted, the analysis shows that the Erikson-Stirling pseudocycle is more efficient than the Carnot cycle in a certain temperature range. It should also be noted that, in contrast to the theoretical Carnot cycle, the implementation of the latter in real heat engines is quite possible, which gives the prospect of using such engines to convert renewable and traditional thermal energy into mechanical energy.
