potential — Any of several different scalar quantities, each of which involves energy as a function of position or of condition; e.g., the fluid potential of ground water [22] … Lexicon of Cave and Karst Terminology
Potential flow — streamlines around a NACA 0012 airfoil at 11° angle of attack, with upper and lower streamtubes identified. In fluid dynamics, potential flow describes the velocity field as the gradient of a scalar function: the velocity potential. As a result,… … Wikipedia
Fluid-structure interaction — (FSI) occurs when a fluid interacts with a solid structure, exerting pressure on it which may cause deformation in the structure and thus alter the flow of the fluid itself. Such interactions may be stable or oscillatory, and are a crucial… … Wikipedia
Potential vorticity — (PV) is a quantity which is proportional to the dot product of vorticity and stratification that, following a parcel of air or water, can only be changed by diabatic or frictional processes. It is a useful concept for understanding the generation … Wikipedia
fluid mechanics — an applied science dealing with the basic principles of gaseous and liquid matter. Cf. fluid dynamics. [1940 45] * * * Study of the effects of forces and energy on liquids and gases. One branch of the field, hydrostatics, deals with fluids at… … Universalium
Potential density — The potential density of a fluid parcel at pressure P is the density that the parcel would acquire if adiabatically brought to a reference pressure P {0}, often 1 bar (100 kPa). Whereas density changes with changing pressure, potential density of … Wikipedia

Potential temperature — The potential temperature of a parcel of fluid at pressure P is the temperature that the parcel would acquire if adiabatically brought to a standard reference pressure P {0}, usually 1000 millibars. The potential temperature is denoted heta and,… … Wikipedia
fluid — fluidal, adj. fluidly, fluidally, adv. fluidness, n. /flooh id/, n. 1. a substance, as a liquid or gas, that is capable of flowing and that changes its shape at a steady rate when acted upon by a force tending to change its shape. adj. 2.… … Universalium
potential — 1. Capable of doing or being, although not yet doing or being; possible, but not actual. 2. A state of tension in an electric source enabling it to do work under suitable conditions; in relation to electricity, p. is analogous to the temperature… … Medical dictionary
