Résumé :

In rotating detonation combustors, the high operational frequency and temperature level (2000- 4000. K) offer the potential of direct power extraction through the MagnetoHydrodynamic effect. In this paper, first of all electrical conductivity and chemical properties are evaluated with an in-house built chemical kinetics library, Mutation++. Those properties are subsequently utilized in a one-dimensional flow solver, equipped with a magnetohy-drodynamic module. A 3D reactive URANS flow solver is used to determine the total amount of MHD power extracted from the combustor. Finally, we perform the analysis of the detonation combustor considering unseeded and seeded flows to enhance the electrical conductivity.
