On the Flight of the Volleyball
J. Dumek, P. Šafařík, Z. Pátek, T. Asai
Abstract:
The paper deals with results of measurements of forces acting on volleyball. Drag coefficients evaluated from measurements in two aerodynamic tunnels are compared. The other force components i.e. lift and side force obtained by experimental investigation with angle of attack related to the axis of rotation are studied.
Keywords:
aerodynamics, drag, forces, lift, measurement, volleyball, wind tunnel
