Effect of Turbulence Intensity on Cross-Injection Film Cooling at a Stepped or Smooth Endwall of a Gas Turbine Vane Passage

The Scientific World Journal, 2014
This study is concerned with a film cooling technique applicable to the protection of the endwalls of a gas turbine vane. In the experiments, cross-injection coolant flow from two-row, paired, inclined holes with nonintersecting centerlines was utilized.

Modelling global offshore turbulence intensity including large-scale turbulence, stability and sea state [PDF]

Wind Energy Science
This study delivers a method and datasets for a global offshore atlas for turbulence intensity (TI) from 10 to 200 m. The method includes both surface-driven three-dimensional boundary-layer turbulence and large-scale two-dimensional turbulence.

Investigating whether the turbulence model from existing small wind turbine standards is valid for rooftop sites

, 2011
The wind energy industry has developed considerably in recent years with regard to large scale wind turbines. However, the small wind turbines (SWTs) are still underdeveloped. The classification of SWTs comes under the standard IEC6140001-2. When a small

Uncertainties in offshore wind turbulence intensity

Journal of Physics: Conference Series, 2019
Abstract In the development, design and operation of wind farms the knowledge of wind turbulence intensity is of paramount importance, particularly at hub height. Given that measurements are rare, turbulence intensities are often determined using simplified formulations.

Systems of intensive vertical vortices in turbulent atmosphere

, 2019
At certain conditions a system of well-separated quasi-point vortices can appear in two-dimensional turbulence. Such system contains main part (almost entire) of the flow enstrophy (mean squared vorticity). Spectral properties of the two-dimensional turbulence in the presence of the system of the quasi-point vortices have been studied using notion of ...

Experimental Investigation of Turbulence Specifications of Turbidity Currents

Journal of Applied Fluid Mechanics, 2010
The present study investigates the turbulence characteristic of turbidity current experimentally. The three-dimensional Acoustic-Doppler Velocimeter (ADV) was used to measure the instantaneous velocity and characteristics of the turbulent flow.
