Book excerpt: "This thesis describes a theoretical and experimental investigation of a two-dimensional, turbulent jet flowing, at incompressible speeds, onto a screen placed at right angles to the flow. Five wire screens with square mesh and open area ratios ranging form 0.34 to 0.66 were tested over a range of Reynolds numbers. Attention was focussed on the loss of momentum of the flow through the screen and the subsequent development of the flow downstream. For the screens with relatively large open area ratios, there was a tendency for the jet profiles to return to a self-preserving shape downstream. For the more solid screens, however, the flow tended to develop downstream as two separate diverging jets. [...]" --
