Exergy Analysis in Hydrogen‐Air Detonation [PDF]

Journal of Applied Mathematics, 2012
The main goal of this paper is to analyze the exergy losses during the shock and rarefaction wave of hydrogen‐air mixture. 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%.
