DNS of compressible pipe flow exiting into a coflow
Direct numerical simulations were conducted of a fully turbulent canonical nozzle/jet configuration. For all cases, the target Reynolds number, based on the jet velocity and diameter, was specified as 7670 and the jetMach number and coflow Mach number were varied. The effect of the nozzle lip on the turbulent flow exiting the nozzle was investigated, with particular emphasis on whether Reynolds stress profiles at the nozzle exit could be collapsed with profiles in the fully developed region, and whether local behaviour in the vicinity of the nozzle exit could be predicted using asymptotic theory. The DNS data were also used to investigate the effect of varying Mach number and coflow on the mean flow and whether the various flow cases could be collapsed using similarity arguments

Abstract
Direct numerical simulations were conducted of a fully turbulent canonical nozzle/jet configuration. For all cases, the target Reynolds number, based on the jet velocity and diameter, was specified as 7670 and the jetMach number and coflow Mach number were varied. The effect of the nozzle lip on the turbulent flow exiting the nozzle was investigated, with particular emphasis on whether Reynolds stress profiles at the nozzle exit could be collapsed with profiles in the fully developed region, and whether local behaviour in the vicinity of the nozzle exit could be predicted using asymptotic theory. The DNS data were also used to investigate the effect of varying Mach number and coflow on the mean flow and whether the various flow cases could be collapsed using similarity arguments
