This review paper presents various researches on the aerodynamic analysis of wind turbine rotor blade through CFD (computational fluid dynamics). An aerodynamic analysis CFD method is good, less expensive and gives the best results. CFD results give good agreement with the experimental data. The wind turbine blades are subjected to various aerodynamic loads, which simulated easily through CFD analysis because experimentally calculation is very complicated. In this study the researchers used various CFD codes which are based on Blade Element Momentum Theory (BEM) and got a good result through these codes.
