The Effect Of Ambient Turbulence On A
Turbulent Plane Jet In A Shallow Coflow
Author(s)
M. McKernan and S. Gaskin
Abstract
The entrapment of ambient fluid into a jet represents the fundamental method by
which dilution and mixing are achieved. For an application such as the
discharge of an effluent into a river or stream, the influence of the ambient
coflow on the extent of entrainment and mixing which occurs becomes
important. The purpose of this study was to investigate the effect of ambient
turbulence on the entrainment into a plane non-buoyant turbulent jet issuing into
a shallow coflowing stream. The experimental study was carried out through a
comparison of a turbulent plane jet issuing into a coflow with low turbulence to
that of a turbulent plane jet issuing into increasingly turbulent coflows.
Completely submerged walls, placed perpendicular to the direction of the coflow
were
