On aerodynamics of baseball pitches: reconstruction of spinning throws, and a lift force model for the knuckleball
Published 2016“…The second part deals with the lift force present in knuckleball pitches, which is caused by the asymmetries on the ball morphology and has an oscillatory behavior varying the seams orientation. We propose a model to compute said force for two-seams (2S) and four-seams (4S) orientations, by means of a coefficient (lift coefficient) depending on the positions of each stitch of the ball seams. …”
