Abstract:A nonstationary flow in a channel with a blow was simulated on the basis of the Reynolds-averaged NavierStokes equations and the two-parameter k-ε model of turbulence. The pressure near the left end of the channel changes by the harmonic law. It was established that the k-ε model of turbulence can be used for calculating the nonstationary flows formed in the indicated channel by a blow.Introduction. The oscillations of the parameters of a working substance in the combustion chamber of a solid-propellant engine… 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.
