WebThis paper presents the first high-order computational fluid dynamics (CFD) simulations of static and spinning golf balls at realistic flow conditions. The present results are shown to capture the complex fluid dynamics inside the dimples which lead to drag reduction versus a smooth sphere, and compare well to previous experimental and ... WebDec 31, 2011 · Prior studies have revealed that golf ball aerodynamics is still not fully understood due to the varied dimple size, shape, depth and pattern. The current study experimentally measured drag ...

WebAerospace Computing Lab - Home WebMay 8, 2024 · 17.1: Effect of dimples. In the previous column, we saw the generation of small vortices on the surface of a golf ball due to dimples. In this column, we will close in on the mechanism of how dimples lower air drag. First, let us look at the flow field around the golf ball without dimples. Figure 17.1 shows the velocity distribution on a cross ...
WebA golf ball usually flies at a high speeds at which the drag of a golf ball is about half of that of a smooth sphere because of dimples on the golf ball surface. Meanwhile, near a golf ball surface, dimples play an important role to trigger the boundary layer transition from laminar to turbulent flow. However, mechanisms of the boundary layer ...
