... Turbulence When the Reynolds number becomes sufficiently large, the non-linear term (u ⋅ ∇ ) u in the momentum equation inevitably becomes comparable to other important terms and the flow becomes more complicated. In almost all cases the equation will have more than one solution and at least one of ...

Deep fracture fluids isolated in the crust since the Precambrian
... mine fluids can be linked to Xe isotope changes in the ancient atmosphere [3] and can be used to calculate a minimum mean residence time for this fluid of ~1.5Ga. We also resolve in all samples a clear 129Xe signal in excess of atmospheric values. Mass fractionation and U fission can be excluded as ...

Fluid dynamics
In physics, fluid dynamics is a subdiscipline of fluid mechanics that deals with fluid flow—the natural science of fluids (liquids and gases) in motion. It has several subdisciplines itself, including aerodynamics (the study of air and other gases in motion) and hydrodynamics (the study of liquids in motion). Fluid dynamics has a wide range of applications, including calculating forces and moments on aircraft, determining the mass flow rate of petroleum through pipelines, predicting weather patterns, understanding nebulae in interstellar space and modelling fission weapon detonation. Some of its principles are even used in traffic engineering, where traffic is treated as a continuous fluid, and crowd dynamics. Fluid dynamics offers a systematic structure—which underlies these practical disciplines—that embraces empirical and semi-empirical laws derived from flow measurement and used to solve practical problems. The solution to a fluid dynamics problem typically involves calculating various properties of the fluid, such as flow velocity, pressure, density, and temperature, as functions of space and time.Before the twentieth century, hydrodynamics was synonymous with fluid dynamics. This is still reflected in names of some fluid dynamics topics, like magnetohydrodynamics and hydrodynamic stability, both of which can also be applied to gases.
