Abstract: Abstract Rocket jet flow and airflow represent a typical mixing layer flow in a combustion chamber of a combined air-breathing propulsion system. Previous studies indicate that highly and weakly compressible mixing layers are similar in…

Abstract: Abstract We consider parallel splitting of a strip composed of two different chains . As a waveguide, the dissimilar-chain structure radically differs from the well-studied identical-chain system. It is characterized by three speeds of the…
