IMPACT OF SKIRT PRESSING ON THE AERODYNAMIC DRAG OF A BADMINTON SHUTTLECOCK

The effects of the various design parameters of the shuttlecock have been attempted to design a synthetic shuttlecock having a similar feature that of feather shuttlecock. Most of the work till date has been attempted to visualize the flow behaviour around the shuttlecock and to obtain the flight trajectory of the shuttlecock through simulation. A little work has been done on changing the design parameter of the shuttlecock. The impact of skirt pressing on shuttlecock has not been studied in detail until now. Reynolds-Averaged Navier strokes (RANS) model was applied to evaluate the performance parameters of the shuttlecock. It has been observed from the study that the addition of radial or axial pressing over skirt decreases drag coefficient, contrary to which when both pressings added together Drag Coefficient increases. Another effect which was studied was the effect of increasing the pressing length overskirt which results in increasing the drag coefficient.
