Geophysical fluiddynamics is the study of naturally occurring, large scale flows on Earth and other planets . It is applied to the motion of fluids in the ocean and outer core , and to gases in the atmosphere of Earth and other planets. Two features that are common to many of the phenomena studied in geophysical fluiddynamics are Rotating reference frame rotation of the fluid due to the planetary rotation and stratification layering . It does not generally include the circulation of the mantle , which is the subject of geodynamics , or fluid phenomena in the magnetosphere . Smaller scale flow features are the province of fields such as hydrology , physical oceanography and meteorology . ref harv Pedlosky 1987 ref Fundamentals Navier Stokes equations Nondimensionalization Fluid dynamic equations can be scaled so that they are controlled by non dimensional parameters.

File Hairpinvortex.jpg 400px thumb Visualization of hairpin vortex structure, made visible by seeding the flow with colored dye. In fluid dynamics , seeding a flow, or a seeded flow, means to introduce particulate s or other foreign substances into an otherwise transparent stream of fluid . These particulates are generally small enough to be carried by the fluid but large enough to be picked up using a flow visualization technique, such as particle image velocimetry PIV . In reference to aerodynamic testing, such as wind tunnel testing, water tunnel testing, or any other test investigating the flow of a fluid which may be invisible to the naked eye, seeding a flow is often the only way to take visual measurements. Simple examples of a seeded flow include the introduction of smoke into a low speed wind tunnel to see the general path of the air, or injecting colored dye into a water tunnel to see secondary flow structures such as hairpin vortices.

It occurs in flows when the local flow speed exceeds the local speed of sound sound speed . More specifically, it is a flow whose Mach number exceeds 1. Explanation of phenomena Shock is formed due to coalescence coalescing coming together of various small pressure pulses. Sound wave s are pressure wave s and it is at the speed of the sound wave the disturbances are communicated in the medium. When an object is moving in a flow field the object sends out disturbances which propagate at the speed of sound and adjusts the remaining flow field accordingly. Clarify date April 2009 However, if the object itself happens to travel at speed greater than sound, then the disturbances created by the object would not have traveled and communicated to the rest of the flow field and this results in an abrupt change of property, which is termed as shock in gas dynamics terminology. Shocks are characterized by discontinuities changes in flow properties such as velocity , pressure , temperature , etc. Typically shock thickness is of a few mean free path s of the order of 10 sup 8 sup m . Shocks are irreversible occurrence in supersonic flow s i.e. the entropy increases .

Unreferenced date December 2009 In atmospheric dynamics and fluiddynamics , a hydrostatic fluid is a fluid in which fluid stresses act isotropic ally and fluid elements are in local equilibrium with one another. Thus, all directional fluid stresses, normally represented as vectors, can be summarized by a scalar physics scalar quantity called the hydrostatic pressure , which can still depend on position. The stress mechanics stress tensor takes on the form math sigma ij p delta ij math , where math p math is the hydrostatic pressure, and math delta ij math is the kronecker delta The equilibrium which exists in a hydrostatic fluid is often the result of a balance between forces that compress the fluid and forces that resist compression. For example, on earth, the atmosphere is compressed against the surface by gravity and supported by its internal energy . This is often referred to as hydrostatic equilibrium .

norefs date March 2010 A jet is an efflux of fluid that is projected into a surrounding medium, usually from some kind of a nozzle , aperture or orifice. Jets can travel long distances without dissipating. In the Earth s atmosphere there exist jet stream s that travel thousands of miles. In the case where the surrounding medium is assumed to be made up of the same fluid as the jet and this fluid has a viscosity then the surrounding fluid near the jet is assumed to be carried along with the jet by a process called entrainment . Some animals, notably cephalopods use a jet to propel themselves in water. Similarly, a jet engine as it name suggests, emits a jet used to propel rocket s, aircraft , jetboat s, and submarine s.

The most developed smart fluids today are fluids whose viscosity increases when a magnetic field is applied. Small magnetic dipoles are suspended in a non magnetic fluid, and the applied magnetic field causes these small magnets to line up and form strings that increase the viscosity.
