Analysis of near wake recovery scale model vawt hybrid wind turbin in wind tunnel

Abstract

CFD simulations of full scale wind turbine have been carried out to predict recovery of wake that occur behind the hybrid VAWT turbine double, which states that recovery starts to occur in plane x/d = 4, verification of this result needs to be done. This study tested and measured the wind speed behind the scale model turbine in the wind tunnel. The purpose of this study was to create a prototype scale model of the VAWT hybrid, test it in the wind tunnel. Statistical methods will be used in this study to process data and determine the recovery position of wake from the VAWT double hybrid. The results show that wake recovery in wind tunnel experiment, in field x/d = 3 with 99%, compare with wake recovery occurs in simulation, shown a show the same trend, but need further investigation with similarity and Reynold number.
