Static Analysis of Transit Points and the Reynolds Number Influence on the Blade of a Wind Power Turbine as Two-Dimensional

Abstract

Airfoil Aerodynamic of the wind power turbines blade is of paramount importance on aerodynamic performance of wind turbines. This research includes a cross section choose of an airfoil employed in wind power turbine blades in the country. Here, the cross-section of 660 kW turbine blade, launched by the Vestas Company in Iran, has been modeled. Airfoil geometry was produced using the software ANSYS WORKBENCH, and has been analyzed fluidly via the software ANSYS FLUENT 15 across the angles of attack "-5" to "20" degrees and in the Reynolds digits of􀫙. 􀫝􀫜 × Ã´Â€Â«ÂšÃ´Â€Â«Â™Ã´Â€Â«ÂŸand 􀫙. 􀫡􀫝 × Ã´Â€Â«ÂšÃ´Â€Â«Â™Ã´Â€Â«ÂŸ along with applying Turbulent flow influence. The effects of Reynolds digits and increase of turbulence have been analyzed over the crossing points' situation. Furthermore, this part of turbine has been tested experimentally in Shiraz wind tunnel and the coefficients of lift, drag, and other properties have been studied in case
