Computational Sports Aerodynamics of a Moving Sphere:Simulating a Ping Pong Ball in Free Flight
Computational Sports Aerodynamics Moving Sphere Simulating Ping Pong Ball Free Flight
2015/7/3
Fluid dynamics associated with many sports involving spheric shaped equipments such as tennis, golf and ping pong balls tends to be very unsteady and viscous, with occasionally transitional behaviors....

2011/9/14
We consider finite deformations of the p + 2-dimensional Schwarzschild geometry which obey the vacuum Einstein equation, preserve the mean curvature and induced conformal metric on a sphere a distance...
Drag force on a sphere moving towards an anisotropic super-hydrophobic plane
Drag force sphere super-hydrophobic
