A note on the radial wall jet with swirl
The aim of this paper is a determination of the space flow geometry of turbulent radial wall jet with swirl by means of a similarity analysis. It is assumed that except for a very thin layer near the wall, the flow field of the turbulent radial wall jet is similar. The wall conditions for a Newtonian fluid flow used in a paper by the present authors [Appl. Sci. Res. 42, 185-196 (1985; Zbl 0566.76028)] - and satisfactory only for a laminar regime - are substituted by a suitable condition often employed in 3-D turbulent boundary layer problems. It is assumed that the direction of the shear-stress resultant is the same as the direction of the mean velocity-gradient resultant.
