“…As shown in [8], in this case the length of transition region reduces to 1-2 jet diameters. [4][5][6][7][8]. The characteristic feature of the jet under consideration is the presence of three inflection points in the inlet velocity profile.…”

“…At large , turbulence transition in circular jets occurs, as a rule, in the immediate neighborhood of the nozzle exit section, within the distance of 1D (D is the nozzle diameter). Several years ago, a compact device for generation of circular air jets which ensures maintenance of laminar flow at (U b is the mean velocity in the inlet stream, ) at distances to ~6D at D = 0.12 m was designed and fabricated in the Institute of Mechanics of Moscow State University [4,5]. In this case, the dimension of the device is equal to approximately only .…”

“…In [11,12] the jet with a long laminar region and the facility forming it are described thoroughly. Hereinafter, the theoretical analysis and experiments are conducted for the flow with Re=5030, based on the diameter D and average velocity (the axis speed Uc=1.5 m/s).…”

“…At the Institute of Mechanics of Lomonosov Moscow State University the facility has been created that generates a submerged jet of 0.12 m in diameter (D) and with a long laminar region ~5D at the Reynolds numbers (Re) in the range 5000 -10000 [11,12]. Such jet provides the possibility to conduct detailed experimental observations of perturbations growth and to compare them with predictions of the linear stability theory applied to velocity profiles at different distances from the orifice.…”
