An experimental study of the effects of pitch-pivot-point location on the propulsion performance of a pitching airfoil [PDF]

, 2016
An experimental investigation was conducted to characterize the evolution of the unsteady vortex structures in the wake of a pitching airfoil with the pitch-pivot-point moving from 0.16C to 0.52C (C is the chord length of the airfoil).

Experimental Study of Airfoil Aerodynamic Behavior under Oscillating Motion in Ground Effect [PDF]

Journal of Applied Fluid Mechanics
When a flying vehicle approaches a water or land surface, it induces changes in the fluid flow field pattern known as the "ground effect." This research analyzes the ground effect phenomenon, exploring its impact on aerodynamic coefficients and flow ...

Magnitude and variability of individual elbow load in repetitive baseball pitching

Scientific Reports, 2023
In baseball pitchers the elbow is exposed to high and repetitive loads (i.e. external valgus torque), caused by pitching a high number of balls in a practice session or game.

Automatic detection of pitching and throwing events in baseball with inertial measurement sensors

, 2017
Purpose: Throwing loads are known to be closely related to injury risk. However, for logistic reasons, typically only pitchers have their throws counted, and then only during innings.
