The thermoeconomic objective function, defined as the total cost per unit power output, is minimized with respect to the cycle temperatures along with the isobaric temperature ratio for a given set of operating parameters. The objective function is found to be an increasing function of the internal irreversibility parameter, economic parameters and the isobaric temperature ratio. On the other hand, there exist the optimal values of the state point temperatures, power output and thermal efficiency at which the objective function attains its minimum for a typical set of operating parameters. Moreover, the objective function and the corresponding power output are also plotted against the state point temperature and thermal efficiency for a different set of operating parameters. The optimally operating regions of these important parameters in the cycle are also determined. The results obtained here may provide some useful criteria for the optimal design and performance improvements, from the point of view of economics as well as from the point of view of thermodynamics of an irreversible Braysson heat engine cycle and other similar cycles as well.<\/jats:p>","DOI":"10.3390\/e6020244","type":"journal-article","created":{"date-parts":[[2008,10,25]],"date-time":"2008-10-25T13:44:42Z","timestamp":1224942282000},"page":"244-256","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Optimum Criteria on the Performance of an Irreversible Braysson Heat Engine Based on the new Thermoeconomic Approach"],"prefix":"10.3390","volume":"6","author":[{"given":"Sudhir Kumar","family":"Tyagi","sequence":"first","affiliation":[{"name":"Department of Physics, Xiamen University, Xiamen 361005, People's Republic of China"},{"name":"Centre for Energy Studies, Indian Institute of Technology, Delhi New Delhi 110016, India"}]},{"given":"Yinghui","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Physics, Xiamen University, Xiamen 361005, People's Republic of China"}]},{"given":"Jincan","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Physics, Xiamen University, Xiamen 361005, People's Republic of China"}]}],"member":"1968","published-online":{"date-parts":[[2004,3,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"121","DOI":"10.1243\/0957650971537042","article-title":"A hybrid gas turbine cycle (Brayton\/Ericsson): an alternative to conventional combined gas and steam turbine power plant","volume":"211","author":"Frost","year":"1997","journal-title":"Proc.
