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. Jet fluid has higher momentum compared to the surrounding fluid medium. 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. These Magnetorheological fluid magnetorheological or MR fluids are being used in the suspension vehicle suspension of the 2002 model of the Cadillac Seville STS automobile and more recently, in the suspension of the second generation Audi TT. Depending on road conditions, the damping fluid s viscosity is adjusted. This is more expensive than traditional systems, but it provides better faster control. Similar systems are being explored to reduce oscillation vibration in washing machine s, air conditioning air conditioning compressors , rockets and satellites, and one has even been installed in Japan s National Museum of Emerging Science and Innovation in Tokyo as an earthquake shock absorber .

Given some input configuration of fluid and scene geometry, a fluid simulator evolves the motion of the fluid forward in time, making use of the possibly heavily simplified Navier Stokes equations which describe the physics of fluids. In computer graphics, such simulations range in complexity from extremely time consuming high quality animations for film & visual effects, to simple real time particle systems used in modern games. Approaches There are several competing techniques for liquid simulation with a variety of trade offs. The most common are Eulerian grid based methods, smoothed particle hydrodynamics smoothed particle hydrodynamics SPH methods, vorticity based methods, and Lattice Boltzmann methods . These methods originated in the computational fluiddynamics community, and have steadily been adopted by graphics practitioners. The key difference in the graphics setting is that the results need only be plausible. That is, if a human observer is unable to identify by inspection whether a given animation is physically correct, the results are sufficient, whereas in physics, engineering, or mathematics, more rigorous error metrics are necessary.

In quantum chromodynamics , the instanton fluid model is a model of Wick rotate d Euclidean quantum chromodynamics. If we examine the path integral formulation path integral of the action, we find that it has infinitely many Maxima and minima local minima , corresponding to varying instanton numbers. It turns out that the dominant contribution to the path integral comes from configurations with consisting of a pool of instantons and antiinstantons. The exponential suppression coming from the increased action is compensated by the increased phase space factor coming from all the instantons. In other words, the Euclidean free energy is minimized by a pool of instantons. We also know that in the presence of an instanton, left handed quarks of each flavor will be produced and right handed quarks annihilated. This evidently will have consequences to the chiral dynamics of the theory. References Citation last Schafer first T. last2 Shuryak first2 E.

In physiology , the term serous fluid is used for various bodily fluid s that are typically pale yellow and transparent, and of a benign nature, that fill the inside of body cavity body cavities . Serous fluid originates from serous gland s, with secretions enriched with protein s and water. Serous fluid may also originate from mixed glands, which contain both mucous and serous cells. A common trait of serous fluids is their role in assisting digestion , excretion , and Respiratory system respiration . In medical fields, especially cytopathology , serous fluid is a synonym for effusion fluid s from various body cavities . There are many causes of effusions which include involvement of the cavity by cancer . Cytopathology evaluation is recommended to evaluate the causes of effusions in these cavities. ref name Shidham Examples Saliva consists of mucus and serous fluid the serous fluid contains the enzyme amylase important for the digestion of carbohydrate s. Minor Von Ebner s glands salivary glands of von Ebner present on the tongue secretion secrete the amylase. The parotid gland produces purely serous saliva. The other major salivary gland s produce mixed serous and mucus saliva. Another type of serous fluid is secreted by the serous membrane s or serosa , two layered membranes which line the body cavities .
