تحلیل انرژی، اگزرژی و اقتصادی موتور احتراق داخلی مجهز به سیستم‌های پرخوران و خنک کن میانی

Exergy analysis is a method of evaluating the contribution proportion of each process on transmission of initial availability of the system and determining the positions of useful energy losses. In this research exergic analysis of an internal combustion engine equipped with turbocharger and intercooler is attended. To do this, at first, the procedure of performance simulation of the system components i.e. engine, compressor, turbine and intercooler is briefly explained. Then by defining exergy terms and using related exergy equilibrium equations for open and closed systems necessary conceptual basis for exergy analysis, is introduced. Also exergo-economic analysis, as a powerful tool for cost study and optimization of complex energy systems is developed by combining the second law of thermodynamics concept with economic view points. The results show that combustion process produces the most proportion of the system irreversibility. Furthermore, regarding exergo-economic parameters, engine has the most suitable performance among the related components of the system.
