Modelagem e simulação numérica de um motor Stirling para aplicações em sistemas solares

Abstract

The numerical simulation is intended to analyze quickly, economically and efficiently the behavior of certain systems, with the aim of enabling optimal solutions and serves as a basis for technological development. This work aims to numerically evaluate the performance of a Stirling engine used in solar systems, with the support of simulation tools, design and optimization, as well as defining and using the mathematical model in accordance with the design methods of first and second order for Stirling engines, in addition to examining the behavior of engine, taking into account the parameters that can be optimized, in order to raise the efficiency of the system. To that end, was used as a method for data collection the bibliographical research, through the study of Dish/Stirling Systems and the Stirling engine SOLO V161, and the computer simulation through the programs SEA, which uses codes in MATLAB language, and EES. The results and theoretical assessments are presented, discussed and compared. From the analysis of the data it was possible to realize besides other relevant information, like the operation variables influence the performance and efficiency of this heat machine. Finally, by means of the study it was possible to confirm the importance of numerical simulation in the study and development of Stirling engines
