New Era Wind Turbine Design

II. COMPONENT OF NEW ERA WIND TURBINE DESIGN In order to extract energy from a larger area of the approaching wind, smaller, sturdier, and faster blades can be used. We try to design a new idea about the shape of fin, cowl, lobed mixer, rotor and stator. There are some of important parts in this new design of wind turbine jet.

Numerical and Experimental Study on Jet Trajectories and

An investigation of the jet trajectories and mixing behavior of venturi-jet mixers, in which turbulent jet injects fluid at an arbitrary angle to mix incompressible fluids, is described in this paper. Numerical results of an incompressible cross flow-jet mixing in venturi-jet mixers are presented and validated against experimental results.

Research on the Rectangular Lobed Exhaust Ejector /Mixer

ejector/mixer systems have received great attention by many researchers in the recent years (Refs. 1-10) and they have been widely applied to the aero-engine area. For example, on the commercial aero-engines, such as JT8D-217C, CFM56-5C and RB211-524G/H, lobed ex-haust ejector/mixer systems had been used to reduce

the lobes, and three large scale vortex rings. The shroud and lobed ejector structure in the back of the proposed wind turbine produced such an effect that the pressure at the wind turbine exit was reduced so that the turbine power output was increased by 240%. It is therefore concluded that the proposed wind
