Abstract

A multi-channel combustion device is provided. The device includes an inlet port, at least one radially partitioned inlet zone within the inlet port, and a plurality of circumferentially spaced combustion chambers in which deflagrative or detonative combustion occurs. The inlet port may have a plurality of separate, circumferentially partitioned inlet zones for supplying fuel and air mixtures to the inlet end of the combustion chambers. Each inlet zone is capable of introducing a different combustible mixture sequentially to a given combustion chamber as the chamber communicates with the inlet zones. The inlet of at least one combustion chamber is radially partitioned. At least one inlet zone is radially partitioned to permit radial stratification within the combustion chambers. The multi-channel combustion device may be a combustion wave rotor or a valved combustor.
