Vortex generator

After vortex generator installation, the flow distribution around blades improves a lot  compared with that before installation.From the theory analysis,it can improve much stability for the old type stalled fan. For the mainstream of the variable speed variable pitch fan.For most popular type fan which is with  propeller shifting and speed shifting performance,it can efficiently improve wind speed,run stably.

For Automobile industry, flow control by using vortex generator, adjusting control position and control parameters, can effectively improve the wake flow pressure, reduce the pressure resistance,so as to effectively reduce the automobile aerodynamic resistance by using the minimum energy input,to improve driving power for the automobiles.

  For windmill fan,the vortex generator is installed on the wing surface to generate small vortexes, so that the airflow separation can be prevented, and the energy lost on the wing is locked on the wing surface, thereby increasing the power generation of the fan and producing economic benefits. The technology has been widely used by foreign manufacturers, such as GE.

For plane, the vortex generators are installed on the it, can effectively prevent the various separations of  airflow within too short time,so as to prevent the stall of the plane, stall angle increases, increase the maximum lift coefficient, increase control performance, Gentle joy stick vibration. 

 At present, we use theoretical analysis and numerical simulation and other research methods.We summed up a set of vortex generator design, experiment, production, installation of mature technology system through the wind tunnel test results and rich experience and actual installation. In the design aspect,our  company experts use the most advanced 2 dimensional 3 dimensional numerical simulation method on the research server to comprehensively verify the layout scheme of the vortex generator. During the test, our company expert guiding team will guide how to install vortex generator system for windmill system.And we will check out the final performance with owner.

We adopt numerical simulation method,use a large and accurate vortex simulation turbulence model, and the accuracy is much higher than that of the traditional industrial turbulence model. In order to obtain accurate aerodynamic information of airfoils used in different blades. We will design the vortex generator through the "wool matrix method - fan blade surface flow field observation experiment" observation results.
