英语百科

Fluid parcel

(重定向自Material surface)

In fluid dynamics, within the framework of continuum mechanics, a fluid parcel is a very small amount of fluid, identifiable throughout its dynamic history while moving with the fluid flow. As it moves, the mass of a fluid parcel remains constant, while—in a compressible flow—its volume may change. And its shape changes due to the distortion by the flow. Note that in an incompressible flow the volume of the fluid parcel is also a constant (isochoric flow).
