Bernoulli levitation

摘要

Bernoulli levitation is the basis of many popular counter-intuitive physics demonstrations. However, few of these lend themselves to a quantitative description without recourse to computational fluid dynamics. Levitation of a flat plate is the exception, and we present an analysis that illustrates several principles of fluid mechanics in a pedagogically useful way.
