01/06/2016  The turbulence characteristics ranged from ∼5% to 25% turbulence intensity and length scales of ∼0.15–0.7 m, corresponding to length scale to turbine diameter ratios of approx. 0.2–1. The turbulence flows were generated using static grids that generated roughly uniform, isotropic flows and could therefore be considered free-stream conditions. The range of turbulence intensities compare ...

How turbulent winds abuse wind turbine drivetrains

05/05/2015  When this turbulence strikes the blades of the next turbine downstream, it creates variable loading in the drivetrain. Occasionally, the wake swirl can align well enough with the downwind turbine rotor to create a momentary torque reversal, especially during high winds or emergency stops. The offshore Horns Rev wind farm produced the well-known industry photo showing the degree of wake effect that can occur. The photo shows the leading-edge turbines causing significant turbulence

IEC 61400 - Wikipedia

Wind classes determine which turbine is suitable for the normal wind conditions of a particular site. Turbine classes are determined by three parameters - the average wind speed, extreme 50-year gust, and turbulence. Turbulence intensity quantifies how much the wind varies typically within 10 minutes. Because the fatigue loads of a number of major components in a wind turbine are mainly caused by

Wind farm - Wikipedia

The faster the average wind speed, the more electricity the wind turbine will generate, so faster winds are generally economically better for wind farm developments. The balancing factor is that strong gusts and high turbulence require stronger more expensive turbines, otherwise they risk damage. The average power in the wind is not proportional to the average wind speed, however. For this reason, the ideal wind conditions would be strong but consistent winds with low turbulence

rooftop and measure the effect of high turbulence intensities (TIs) around the building on its performance. Here we observed far higher TIs than are specified in the MWT design standard (IEC 61400-2 Ed. 3). For example, we found TIs ranging from 5–55% at wind speeds of around 5 m/s. Our tests also revealed that the turbine’s output power lay above the manufacturer’s power curve at low ...

On the Influence of High Turbulence on the Convective

High-pressure turbine vanes and blades are subjected to a turbulent combustor flow affecting the heat transfer and boundary layer transition, hence, the temperature distribution. The accurate prediction of the temperature distribution is crucial for a reliable design and cooling implementation. Engine-representative measurements are hence mandatory for improving design tools.

Fish-friendly turbines

TURBULENCE/SPLASH. High shear, turbulence and splash will all contribute to stress for the fish. The design objective should be to maintain as smooth a flow pattern as possible. ABRASION RISK. Some improvements can be achieved by the use of smooth internal surfaces. Abrasion risks are mainly reduced by reducing transit time and the relative velocities between fish and the components of the device.

What is the wind class of a wind turbine? - Renewables First

A Wind Class 3 turbine is designed for an easy life with average wind speeds up to 7.5 m/s, and these turbines typically have extra-large rotors to allow them to capture as much energy as possible from the lower wind speeds they are subjected to. Wind Class 2 turbines are for windier sites up to 8.5 m/s average, and are the most common class of wind turbines available. Wind Class Class 1 ...

The opening of the turbine gate also results, of course, in an immediate rush of water out the bottom of the tank and through the turbine, and the resulting turbulence in the pit is obvious. During the restoration of the mill in the 1970s, the turbine was dug out the accumulated mud and debris of 30-plus years of freshets and dam breaches.
