Özet
The paper presents the computational method and results of 2D and 3D numerical simulations of the flowfield in Continuous Detonation Wave Engine (CDWE) chambers of different geometries. Numerical simulations have been performed using a detailed thermochemical model of H2-O2 mixture and a high-resolution Euler code with the Adaptive Mesh Refinement (AMR) method. 2D and 3D flowfields are described and their comparative analysis is conducted in order to demonstrate 3D effects. It has been found that the 3D flow has specific features due to the detonation reflection from the outer cylindrical wall. The dependence of 3D effects on the chamber diameter and width is investigated. © 2011 by CNRS and MBDA France.
