Description

In this project, the movement of the golf ball due to the impact force of 200 Newtons with an angle of 30 degrees has been investigated, and the movement path of the ball has been determined using ANSYS Fluent software. We perform this CFD project and investigate it by CFD analysis.

The present model is designed in 3-D using the Design modeler. The geometry is related to a golf ball placed inside a domain.

The meshing of this present model has been generated by ICEM software. The total cell number is more than 945765.

Also, due to the nature of the present problem, the transient solver has been enabled.

Golf Methodology

In this project, a golf ball movement with an aerodynamic point of view has been studied. The force which is applied to the ball is equal to 200 N. The golf ball displacement due to the impact has been studied in terms of time.

Therefore, to simulate the free motion of the golf ball within the domain, the Dynamic mesh option has been enabled. Due to this motion, the quality of the mesh cells will deteriorate as time passes.

Thus, the smoothing and remeshing sub-models have been enabled to create high-quality mesh whenever the old mesh quality is not suitable for the continuation of the solution. Also, the six DOF options can model all the possible motion types for the golf ball.

Moreover, the SST k-omega model is used to solve the turbulent fluid flow equations due to its advantage in predicting flow patterns near and far from the surfaces.

Golf Conclusion

After the simulation, two- and three-dimensional contours related to pressure and velocity at different flow times are obtained. For instance, as seen in the pressure contour, the front region where the pressure has increased denotes the stagnation point.

In contrast, the rear part where the pressure has decreased indicates the wake region where the flow is separated from the golf ball's surface.
