RESUMO

The classical Chapman-Jouguet (CJ) theory considers the propagation of combustion waves disregarding the effects of chemical kinetics and wave structure. The CJ model assumes one-dimensional steady flow, ideal gas and sonic conditions at the products. Since extremely high temperatures and pressures can be attained during the combustion wave propagation, real gas effects can be become significant. This work extends the application of the CJ classical model for real gases, especially for the Noble-Abel and van der Waals gases. Analytical expressions are presented for the properties before and after the waves, including ratios of pressures, temperatures, specific volumes, velocities, Mach numbers and stagnation conditions. The effects of covolume, intermolecular forces and specific heats are verified on the Hugoniot curves and on the thermodynamic properties across the combustion waves.
