The paper focuses on the factors (such as oar span、ratio of kettle and oar diameter)which effect on fluid field of the agitator in terms of Fluent,and then brings rofward the improvement places of the internal structure.

The paper aims to optimizing structure on the basis of agitation result affected by some factors (such as oar span) of agitator internal structure by virtue of Fluent sofeware, then bring up improvement measures of the structure.

The influence of Reynolds number and different distance between propeller and rudder on the uniformity of nominal wake of submarine were studied.

Study on the blade pitch control of electrically controlled rotor in hover

When the wind speed is above the rated value,pitch angle is regulated to maintain the constant power output and the constant rotor speed.

In the case of the consideration of angle of attack,propeller pitch angle,yawing rotation,gravity and moment of inertia,a mathematical model based on static analysis is put forward,which is used to study loads of the blade bearing system of a wind turbine.

Large-scale variable speed constant frequency wind generation system usually adopts adjustable pitch control technology in order to ensure output power above the rated power and safety of the system.

The numerical simulating the 3D internal and external mixed flow fields of adjustable pitch horizontal axis wind turbine on conditions of the dynamic parameters was worked out.
