Ексергетичний аналіз двигунів

Abstract

UA: Зроблений аналіз термодинамічних і сучасних ексергетических методів різних процесів і систем. Проведений ексергетичний аналіз двох типів газотурбінних установок, які працюють по простому циклу і регенеративному циклі. Проведений розрахунок ексергії на вході і виході в окремих елементах газотурбінної установки, а також втрати ексергії в цих елементах.

EN: Thermodynamic analysis plays an important role for the analysis of any process, along with the technical and economic analysis. Almost all indicators take into account the thermodynamic efficiency of the energy conversion process according to the first law of thermodynamics, and does not take into account the features of the second law. According to the second law of thermodynamics, the energy can not be completely converted into useful work. But there is a figure with which it is possible to take into account this feature - Exergy. This indicator allows to consider features of the second law of thermodynamics and highlight the part of the energy that can not be used as a result of gas-dynamic phenomena, and makes it possible to quantify the influence of nonequilibrium thermodynamic processes in the energy conversion efficiency. The analysis of thermodynamic and modern exergetically methods of various processes and systems. Produced exergy analysis of two types of gas turbines, which operate on a simple cycle and regenerative cycle. The calculation of exergy input and output in separate elements of the gas turbine, as well as the loss of exergy in these elements.
