Biomechanics investigation on soccer scoring techniques (SSTs) has a relatively long
history. Until now, there have been 43 SSTs identified. Yet, the body of biomechanical …

The term knuckleball in sporting jargon is used to describe a ball that has been launched
with minimal spin, resulting in a trajectory that is erratic and unpredictable. This …

Surface patterns on objects are important in aerodynamics. We show how surface patterns
on volleyballs modify their aerodynamic performances. Conventional volleyballs with six …

The aerodynamic forces acting on a baseball are those produced by the contact between
the ball and the air, and are defined by the initial conditions of the pitch. It is well known that …

The chiral nature of a badminton shuttlecock is responsible for its counter-clockwise
spinning as it naturally propagates through the air. This induces a dissymmetry between left …

The drag crisis in flow past a sphere is modeled within the framework of the recently
formulated scale-resolving hybrid RANS− LES approach, which includes a semi-empirical …

The chiral nature of a badminton shuttlecock is responsible for its anti-clockwise spinning as
it naturally propagates through the air. This induces a dissymmetry between left-handed and …

Abstract Major League Baseball tracks every pitch of every game and provides the public
with access to a significant amount of data for each pitch. This level of data availability is not …

The knuckleball is perhaps the most enigmatic pitch in baseball. Relying on the presence of
raised seams on the surface of the ball to create asymmetric flow, a knuckleball's trajectory …

This paper reviews published works of the field of badminton research within the past 50
years, focusing primarily on the design and flight dynamics of shuttlecocks to identify any …
