ANSYS CFD Analysis: Comparative Study of Fluid Flow Over Two Balls

This project report presents a comparative analysis of fluid flow over a golf ball and a normal sphere using ANSYS Fluent CFD software. The study investigates the behavior of these objects at different speeds (30, 300, and 600 m/s) and Reynolds numbers. The report details the design of both ball geometries in SolidWorks, followed by the simulation setup in ANSYS, including mesh generation, boundary conditions, and material properties. The analysis focuses on key parameters like drag force, turbulence, and pressure distribution. The project also discusses the theoretical concepts of Newtonian and non-Newtonian fluids, computational fluid dynamics, and the significance of the drag coefficient. The results, presented in tabular form, compare the aerodynamic characteristics of the two ball types, highlighting the impact of surface irregularities and flow separation. The report concludes with an assessment of the challenges and outcomes of the simulations, offering insights into the aerodynamic performance of golf balls and spheres under varying flow conditions. The project provides a detailed breakdown of the simulation process, mesh information, boundary conditions, and physics reports, providing a comprehensive analysis of the fluid flow phenomena.
