Interaction of a wall-jet with a shear flow
An experimental investigation of a flow field resulting from the interaction between a spreading turbulent wall jet on a smooth surface and a shear flow was conducted. The combined flow was formed by a downward circular jet penetrating perpendicularly a moving shear stream confined within a constant-area open channel. A hot-wire survey of mean velocity and turbulence intensity was carried out. A similar variation of mean velocity was found to exist on either side of the axis of the impinging jet, provided that appropriate characteristic scales were used. Similarity was obtained by dividing the ...
