Flow around a golf ball is numerically simulated using an unstructured grid method. The golf
ball surface with 480 dimples is modeled by CATIA-CAD software. The surface is …

This 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 …

The flow around a golf ball is studied using direct numerical simulation (DNS). An immersed
boundary approach is adopted in which the incompressible Navier-Stokes equations are …

The drag on a golf ball can be reduced by dimpling the surface. There have been few
studies, primarily experimental, that provide quantitative information on the details of the …

Golf ball flight is affected by rotation of the ball (lift generation) and dimpling on the surface
(drag reduction). Direct Numerical Simulation (DNS) is being developed for the flow around …

In order to understand the role of surface dimpling on the flow over a golf ball, direct
numerical simulations (DNS) are conducted within the framework of an immersed boundary …

The football game is the most popular, played, and loved sport around the world. The advent
of technological breakthroughs and the continuous increase in consumer demand have led …

Turbulent flow around a 43-mm diameter smooth sphere with 245 suction and blowing holes
and a golf ball with 245 dimples was simulated. The holes and dimples were 0.3 and 3.7 …

The flow over a stationary golf ball has been numerically investigated by conducting large-
eddy simulations in the subcritical, critical and supercritical regimes. A direct comparison of …

Fluid dynamics plays a significant role in many sports, principally affecting the trajectory of
the associated ball. Boundary layer theory can be used to explain why some of these effects …
