Description

Total mean wind forces and local peak pressures on wind turbine nacelles were measured in the wind tunnel experiment in order to account for more accurate wind load on nacelle and panel loads on its enclosure. Based on the measurements, empirical formulae for the force coefficients and distribution of peak pressure coefficients are proposed for the safety assessment. Mean drag coefficients in GL Guideline 2003 seem to be conservative rather than proposed values, however, pressure coefficients recommended in the guideline appear to be considerably underestimated compared with results in this study, especially the values of negative peak pressure coefficients, whose distributions are kind of similar to that on roof in BSLJ and in AIJ recommendations, are larger than that in BSLJ and AIJ recommendations on some regions.
