A fluid control system includes a deformable surface that covers a body in at least a first direction and a second direction. The first direction is orthogonal to the second direction. The deformable surface includes a bottom side that faces the body and a top side that is opposite the bottom side. The fluid control system also includes at least one deformer between the deformable surface and the body. The at least one deformer is configured to modify a boundary layer of a fluid that is flowing over the deformable surface by selectively deforming the top side of the surface.
一种流体控制系统,包括在至少第一方向和第二方向上覆盖主体的可变形表面。第一方向与第二方向正交。可变形表面包括面向主体的底侧和与底侧相对的顶侧。流体控制系统还包括在可变形表面与主体之间的至少一个变形器。所述至少一个变形器被配置为通过选择性地使表面的顶侧变形来修改在可变形表面之上流动的流体的边界层。
