 Example sentencesExamples
-  Spence studied a two-dimensional airfoil placed in an inviscid, incompressible, steady fluid flow, in particular a thin jet coming from its trailing edge of the airfoil.
 -  For the high Reynolds numbers commonly associated with insects, birds, and fish, these propulsive forces are generally well described by inviscid flow theory.
 -  The actual model we use is that of a thin elastic plate that overlies an inviscid fluid.
 -  If viscosity is artificially added in an inviscid model, it has only a small effect on performance.
 -  In addition, the postulated role of vorticity production near the head is at variance with inviscid, irrotational models.
