**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

**Aerodynamic potential flow code** — Aerodynamic potential flow or panel codes are used to determine the velocity and subsequently the pressure distribution on an object. This may be a simple two dimensional object, such as a circle or wing and it may be a three dimensional vehicle … 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

**Flow measurement** — is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. Positive displacement flow meters acumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow. Other flow… … 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

**Flow cytometry** — Analysis of a marine sample of photosynthetic picoplankton by flow cytometry showing three different populations (Prochlorococcus, Synechococcus, and picoeukaryotes) Flow cytometry (abbreviated: FCM) is a technique for counting and examining… … Wikipedia

**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

**Flow velocity** — In fluid dynamics the flow velocity, or velocity field, of a fluid is a vector field which is used to mathematically describe the motion of a fluid.DefinitionThe flow velocity of a fluid is a vector field: mathbf{u}=mathbf{u}(mathbf{x},t)which… … Wikipedia

**Flow battery** — A flow battery is a form of rechargeable battery in which electrolyte containing one or more dissolved electroactive species flows through a power cell / reactor that converts chemical energy to electricity. Additional electrolyte is stored… … Wikipedia

**Flow-based programming** — In computer science, flow based programming (FBP) is a programming paradigm that defines applications as networks of black box processes, which exchange data across predefined connections by message passing. These black box processes can be… … Wikipedia
