This work deals with the fluid dynamic analysis of subsonic, viscous flows characterized by low Reynolds numbers over various wing sections, utilizing advanced Computational Fluid Dynamics tools, including ANSYS-FLUENT, SU2, and XFoil tools. The primary goal extends beyond a mere exploration of flow characteristics; it aims to undertake a comprehensive investigation into the complex phenomenon of separation and the intricate formation of laminar bubbles. The research delves into the intricate dynamics of airflow around wing surfaces, seeking not only to characterize the separation patterns and laminar boundary layers but also to unravel the underlying mechanisms governing these phenomena. By scrutinizing the interplay of aerodynamic forces and boundary layer dynamics, the study endeavors to contribute valuable insights that can inform design considerations for enhanced performance under conditions of low Reynolds numbers. This holistic approach underscores the importance of a detailed understanding of fluid dynamics in optimizing the aerodynamic efficiency of wing profiles, particularly in the challenging regime of low Reynolds numbers.
