First, detonation parameters (pressure, temperature, density, and species mass fraction) are calculated for three cases where the hydrogen mass fraction in air is 1.5%, 2.5%, and 5%. Then, exergy efficiency is used as objective criteria of performance evaluation. A two\u2010dimensional computational fluid dynamic code is developed using Finite volume discretization method coupled with implicit scheme for the time discretization (Euler system equations). A seven\u2010species and five\u2010step global reactions mechanism is used. Implicit total variation diminishing (TVD) algorithm, based on Riemann solver, is solved. The typical diagrams of exergy balances of hydrogen detonation in air are calculated for each case. The energy balance shows a successive conversion of kinetic energy, and total enthalpy, however, does not indicate consequent losses. On the other hand, exergy losses increase with the augment of hydrogen concentration in air. It obtained an exergetic efficiency of 77.2%, 73.4% and 69.7% for the hydrogen concentrations of 1.5%, 2.5%, and 5%, respectively.<\/jats:p>","DOI":"10.1155\/2012\/502979","type":"journal-article","created":{"date-parts":[[2012,6,6]],"date-time":"2012-06-06T21:00:58Z","timestamp":1339016458000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Exergy Analysis in Hydrogen\u2010Air Detonation"],"prefix":"10.1155","volume":"2012","author":[{"given":"Abel","family":"Rouboa","sequence":"first","affiliation":[]},{"given":"Valter","family":"Silva","sequence":"additional","affiliation":[]},{"given":"Nuno","family":"Couto","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2012,6,6]]},"reference":[{"key":"e_1_2_7_1_2","doi-asserted-by":"publisher","DOI":"10.2514\/1.9178"},{"key":"e_1_2_7_2_2","doi-asserted-by":"crossref","unstructured":"DavenasA.
