在轴线垂直于气流的圆柱体上，通过从一个或多个狭缝中吹出一片切向绕上表面的空气，就可以产生升力。这种升力可以通过将外部无粘流场与按Spalding统一边界层理论计算的分离点相匹配来估计。该理论很好地再现了实验结果，除非在某些特殊情况下进行了充分的讨论。
Lift can be generated on a circular cylinder with its axis normal to an air flow by blowing a sheet of air tangentially round the upper surface from a narrow slot or slots. This lift force may be estimated by matching the external inviscid flow field with separation points calculated by Spalding's unified boundary-layer theory. The theory reproduces experimental results reasonably well, except in certain special conditions fully discussed.
