• This work presents a three-dimensional investigation of the performance prediction of the operation of the vertical axis wind turbine. The analysis was carried out for the micro-turbine equipped with the Savonius rotor. The applied methodology was based on the Computational Fluid Dynamics (CFD) and used the Finite Volume method to solve the unsteady Reynolds Averaged Navier–Stokes equations. We concentrated our investigations on the influence of the turbulence modelling methodology on the simulation results. The analysis considers most of the URANS turbulence models, starting with the commonly used two equation models like \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$k-\epsilon $$\end{document} or \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$k-\omega $$\end{document} SST to the Reynolds Stress Models with quadratic pressure strain modelling. The results show the influence of turbulence models on the results of the predicted flow field and wind turbine performance.
