Abstract:A three-dimensional (3D) simulation of N 2 /H 2 mixing for a coaxial injector under a supercritical pressure of 10 MPa is conducted using a highorder numerical method. Two outer H 2 jets with injection temperatures of approximately 52 and 462 K are applied while an inner N 2 jet with an injection temperature of approximately 97 K is applied. The mean and §uctuation properties and instantaneous §ow ¦elds are discussed in order to characterize the detailed mixing features for the two injection conditions. A clea… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
