Analysis of aerodynamic characteristics of various airfoils under subsonic flow under ground effect

In this comprehensive study, we utilize ANSYS Fluent, a sophisticated fluid dynamics simulation tool employing the finite volume method, to address intricate aerodynamic computations. Leveraging ANSYS Meshing, we meticulously craft precise geometric models and meshes for airfoils, ensuring the fidelity of our simulations. This meticulous attention to detail is crucial for accurately capturing the complex aerodynamic phenomena involved in ground effect scenarios. Our research delves into the aerodynamic attributes of various airfoils, particularly under subsonic ground effect conditions. We conduct a rigorous comparative analysis of the pressure distribution, drag coefficient, and lift coefficient for the NACA4412, NACA0012, and RAE6-9CK airfoils. By analyzing these parameters, we gain a deeper understanding of how different airfoil designs interact with the ground, which is essential for optimizing the performance of ground-effect aircraft. The insights derived from this analysis are pivotal for refining the design of ground-effect aircraft. They reveal areas for improvement in current designs and guide the development of new aircraft models. Additionally, these insights underpin the rigorous development and testing of novel aircraft models, ultimately enhancing their performance, efficiency, and operational prowess. Overall, this research contributes significantly to the progression of aerospace engineering and the aviation sector. It provides a foundation for future research and development efforts in ground-effect aircraft and has the potential to lead to significant advancements in the performance and efficiency of these aircraft
