摘要:
This paper represents an extension of the results of an original paper on the subject [Am. J. Phys.57, 654–657 (1989)]. Here an experiment, originally performed by Titcombetal., to demonstrate the inverse sprinkler effect is described and analyzed. It is shown that, in a water reservoir, the angular momentum of the sprinkler head is approximately equal and opposite that of the fluid in the sprinkler arms. However, in an air reservoir, one must consider the effects of both turbulence and the motion of the reservoir. Both effects result in a steady‐state acceleration of the inverse sprinkler in a direction opposite that of the normal sprinkler. Also presented is a more detailed analysis than the one given in the original paper to explain the steady‐state behavior of the inverse sprinkler.
