| Popis: | Power generation is increasingly a pertinent concern in today's rapidly evolving world. One method of generating power involves utilizing wind vanes to capture wind energy from coastal or elevated locations. This study investigated the thermos-aerodynamic performance of wind turbine for optimal blade performance geometry. The study utilized Star CCM+ commercial software to computationally model the airfoil geometry of NACA wind blades. The design profile for this research was tapered and marginally twisted in the span wise direction toward the downstream of the airfoil. This enabled the profile to be simulated at multiple angles of attack, specifically 0, 5, and 10 degrees. The primary boundary conditions for the domain model encompass a velocity input, pressure outlet, ambient temperature, turbulence intensity, and a no-slip condition at the wall. On average, three million meshes were created with fifteen prism layers on the blade's wall. The convergence was guaranteed with blade wall Y + < 1. The result indicated optimal performance when angle of attack are position between 5 and 10 degrees. Contrary to previously projected operational velocity of3.45 mis the blade performed at lower environmental wind velocity of 1.85 mis. The airfoil exhibits enhanced performance at this angle of attack, accompanied by moderate pressure penalty, noise, and reliability concerns. |
