Description
This paper presents an educational approach to Computational Fluid Dynamics (CFD) simulation, focusing on the analysis of flow around an American football using ANSYS Fluent. The study aims to enhance students’ understanding of fluid flow phenomena, aerodynamic behavior, and the practical application of CFD tools in engineering education. The approach integrates theoretical knowledge of fluid mechanics with hands-on simulation exercises, encouraging learners to explore key concepts such as turbulence modeling, boundary layer formation, and wake dynamics.
The methodology involves creating a 2D model of an American football, defining appropriate boundary conditions for airflow, and performing steady-state and transient simulations at various Reynolds numbers. The results illustrate the pressure distribution, velocity contours, and vortex structures around football, highlighting the effects of its geometry and surface orientation on drag and lift forces. Visualization of the flow field supports conceptual learning by linking theoretical principles—such as Bernoulli’s equation and flow separation—to observable simulation outcomes.
The educational framework emphasizes guided experimentation, interpretation of numerical results, and critical analysis of simulation accuracy. By integrating ANSYS Fluent into coursework, students develop both technical and analytical skills, fostering a deeper appreciation for CFD as a design and research tool. The study concludes that using an engaging and relatable example, such as the American football, enhances motivation and conceptual retention in engineering education. This teaching approach can be adapted for various fluid flow applications, serving as a model for modern CFD-based learning environments that bridge theory and practice effectively.
