Wind tunnel test results for a 2/4.5 scale MEXICO rotor
Cho, Taehwan; Kim, Cheolwan - In: Renewable Energy 42 (2012) C, pp. 152-156
This paper presents the wind tunnel test results from MEXNEXT, an IEA wind task for analyzing the measurements which have been taken in the EU project ‘MEXICO’. A 2/4.5 scaled model of ‘MEXICO’ rotor was tested in the KARI low wind tunnel with 5 × 3.75 m2 open jet test section. The...
