Abstract Purpose The aim of this paper is to assess the ability of a stress-blended eddy simulation (SBES) turbulence model to predict the performance of a three-straight-bladed vertical axis wind turbine (VAWT). The grid sensitivity study is condu... Read More about Assessment of stress-blended eddy simulation model for accurate performance prediction of vertical axis wind turbine.

The effect of gurney flap on flow characteristics of vertical axis wind turbine (2020)
Journal Article
Syawitri, T. P., Yao, Y. F., Yao, J., & Chandra, B. (2020). The effect of gurney flap on flow characteristics of vertical axis wind turbine. International Journal of Modern Physics B, 34(14n16), https://doi.org/10.1142/S0217979220401074

Recently, the Gurney Flap (GF) has been used to improve the performance of Horizontal Axis Wind Turbine (HAWT) by enhancing its lift coefficient. Compared to HAWT, research on GF application for Vertical Axis Wind Turbine (VAWT) is very limited. More...
