The design of aerial vehicles for Mars is challenged by the planet’s extremely thin, low-density atmosphere, which complicates lift generation and flight stability, especially under dynamic stall conditions. This study investigates the effect of surface cavity-based passive flow control on the aerodynamic performance of a NACA 0018 airfoil under Martian atmospheric conditions using CFD simulations in ANSYS Fluent. Semi-circular cavities of uniform depth are positioned at 10%, 45%, and 75% of the chord length to influence boundary layer development and flow separation. Simulations are conducted over angles of attack ranging from 0° to 20°, evaluating lift, drag, and stall characteristics. The results aim to assess the effectiveness of cavity integration in delaying flow separation, reducing dynamic stall effects, and improving aerodynamic efficiency. This research contributes to the development of stable and energy-efficient aerial systems for future Mars exploration.
