👉 In physics, a "bouffant" is a type of surface element used in fluid dynamics to describe the shape of an object. It is defined as the average pressure distribution around a point on a body or surface with respect to an infinitesimal volume element. Bouffants are often used to model objects that have thin walls and high pressures, such as airfoils, wings, or pipes. They can also be used in hydrodynamics to describe the shape of water waves or
