Investigation of the Aerodynamic Characteristics of a Small Horizontal Wind Turbine Blade with Open-Source Software Using Advanced Turbulence Modelling

Harvesting wind energy with wind turbine utilization is very important for the renewable sources industry. The maximization of a wind turbine efficiency is closely linked to the air flow characteristics around the wind turbine blades. As a result, the optimization of the flow development around the...
