Abstract
This study presents a numerical investigation of airflow through a G-shaped channel, focusing on the influence of geometric parameters on pressure distribution and velocity field development. A three-dimensional CFD model was developed to analyze three channel configurations under identical boundary conditions, with an inlet velocity of 10 m/s and atmospheric pressure at the outlet. The results reveal significant pressure redistribution in the curved section and localized acceleration of the airflow near the inner wall, where velocity increases of up to 49% were observed. The findings demonstrate the strong effect of curvilinear geometry on flow energy transformation and support potential applications in adaptive wind turbine systems.
