Trailing vorticesLaminar flowLifting surfacesPressure gradientsFlow fieldsAxial flow in the core of laminar steady trailing vortex from the tip of a semi-infinite lifting wing is analyzed, assuming that the pressure gradient is determined by the swirl velocities of an ideal infinite line vortex. The...

The use of existing large pumping station equipment for upstream residual water reverse power generation is an unrealized yet valuable renewable energy project. At present, some large axial flow pump stations have begun to perform reverse power generatio
Thus, the dominant sound source mechanisms shift with the change in the operating condition [3], [4]. At the design operating point of the fan, no significant flow disturbances develop at the leading edge. Consequently, the blade trailing edge noise sources, such as the turbulent boundary ...
flow. Moreover, the provision of a continuously decreasing diameter in the second cylinder section down to the leading edges of the impeller blades creates a further acceleration stretch which, in connection with the impeller hub, causes the incident flow to be even and free of vortices over ...
Flow path used for this rotor is same as that of NASA Rotor 37. The profiles are stacked along a radial line through the center of gravities of the profiles. This has resulted in desired geometry, without lean and sweep. Slight modification is made in terms of stagger angle of the tip ...
An axial flow fan blade (11) having an enhanced tip (12, 12') to reduce or eliminate tip vortices and therefore vortex induced noise. The enhancement is a rounded body extending from the blade tip and

Additionally, in this particular embodiment the fluid supply system 58 is located outside of the bearing case 48, although it could be moved inside bearing case 48. One of the advantages of the titling bearing pad 26 is that the pressure and consequently the flowrate at which the fluid ...
A turbine stator vane (41) for use in an axial flow gas turbine. The vane has an aerofoil the pressure face of which is convex between platform (45) and tip
