111Contrast-enhanced ultrasound — (CEUS) is the application of ultrasound contrast medium to traditional medical sonography. Ultrasound contrast agents rely on the different ways in which sound waves are reflected from interfaces between substances. This may be the surface of a… …
112Computational Aeroacoustics — While the discipline of Aeroacoustics is definitely dated back to the first publication of Sir James Lighthill[1][2] in the early 1950s, the origin of Computational Aeroacoustics can only very likely be dated back to the middle of the 1980s.… …
113Boundary-layer thickness — This page describes some parameters used to measure the properties of boundary layers. Consider a stationary body with a turbulent flow moving around it, like the semi infinite flat plate with air flowing over the top of the plate. At the solid… …
114Transtibial prosthesis — A transtibial amputation (sometimes one sees transtibal amputation ) is an amputation above the foot but below the knee.Transtibial amputees have the greatest hope of regaining normal mobility. The knee is the part of the leg involving the most… …
115AUSM — stands for Advection Upstream Splitting Method. It is developed as a numerical inviscid flux function for solving a general system of conservation equations. It is based on the upwind concept and was motivated to provide an alternative approach… …
116Metering pump — A metering pump is a pump used to pump liquids at adjustable flow rates which are precise when averaged over time. Delivery of fluids in precise adjustable flow rates is sometimes called metering. The term metering pump is based on the… …
117Acoustic analogy — Acoustic analogies are applied mostly in numerical aeroacoustics to reduce aeroacoustic sound sources to simple emitter types. They are therefore often also referred to as aeroacoustic analogies.In general, aeroacoustic analogies are derived from …
118Earth quake bomb — The earth quake bomb was a concept that was invented by the British aeronautical engineer Barnes Wallis before World War II and subsequently developed and used during the war against strategic targets in Europe.DevelopmentWallis realized that the …
119Dr.DivX — Dr. DivX is an application created by DivX, Inc. that is capable of transcoding many video formats to DivX encoded video.VersionOriginal versionDr. DivX was originally a closed source encoding application that was based upon royalty charging… …
120Spalart-Allmaras Turbulence Model — Spalart Allmaras model is a one equation model for the turbulent viscosity. Original model The turbulent eddy viscosity is given by: u t = ilde{ u} f {v1}, quad f {v1} = frac{chi^3}{chi^3 + C^3 {v1, quad chi := frac{ ilde{ u{ u}:frac{partial… …
