Reducing the standoff to S = 6 mm (= 20×D) seems to further suppress turbulence development, as shown in Figure 5 where even at Re = 1464 there is no obvious sign of turbulent …

The first phase of the study involved evaluation of the classical analysis of the structure of steadyWebbWhen a jet is formed parallel to a wall, it is called a wall jet, as shown in Fig. P4-55. The jet origin can be thought of as a source of momentum, and further down the wall the velocity profiles are similar. Glauert (1956) showed that both plane and axisymmetrical wall jets satisfy the same ordinary differential equation for laminar flow: $$
