A Evaluation Method of Turbulence Intensity by CFD for Site Conformity Assessment

Abstract

From FY2012 to FY14, in development of site conformity assessment procedures related to wind energy system, a site conformity assessment method for the wind turbine installed at a specific site has been  developed. In this paper, the site conformity assessment method related to the wind conditions at specific site basing on the Guidelines for Design of Wind Turbine Support Structures and Foundations [2010] is shown. As evaluation method of turbulence intensity, the computational fluid (CFD) analysis was applied and the results of comparison and verification of the field measurement data are shown.
