It has been shown that the force acting on a circular cylinder changes discontinuously as the Reynolds number changes in the critical range of the Reynolds number. The force acting on a sphere, however, has so far been reported as to change continuously in this range. It was found for the first time that the force acting on a sphere also changes discontinuously by this experiment, where the flow speed of the windtunnel was varied very small step by step. Flow visualization was made by means of smoke method and the reason for the discontinuous change of aerodynamic force was investigated.
