Wake

In fluid dynamics, a wake may either be:

or both.

Wake effects caused by viscosity

The wake is the region of disturbed flow (often turbulent) downstream of a solid body moving through a fluid, caused by the flow of the fluid around the body.

For a blunt body in subsonic external flow, for example the Apollo or Orion capsules during descent and landing, the wake is massively separated and behind the body is a reverse flow region where the flow is moving toward the body. This phenomenon is often observed in wind tunnel testing of aircraft, and is especially important when parachute systems are involved, because unless the parachute lines extend the canopy beyond the reverse flow region, the chute can fail to inflate and thus collapse. Parachutes deployed into wakes suffer dynamic pressure deficits which reduce their expected drag forces. High-fidelity computational fluid dynamics simulations are often undertaken to model wake flows, although such modeling has uncertainties associated with turbulence modeling (for example RANS versus LES implementations), in addition to unsteady flow effects. Example applications include rocket stage separation and aircraft store separation.

Quit (band)

Quit is a pop-punk band from Miami, Florida, formed in 1988. Quit was founded by Andre Serafini, Russell Mofsky and Addison Burns. Quit has released one studio album and been on numerous compilations and one DVD compilation. Quit released Earlier Thoughts in 1990 when most of the members were 18 and 19 years old. Quit has played shows with Green Day, Helmet, and Fugazi. Quit has recorded over four full-length albums of material.

History

Quit was part of the late 1980s to mid 1990s Miami music scene and local punk music scene. Band members hung out at skate ramps, surfed, and went to local shows and house parties mainly in one southern part of Miami. Quit was formed in the summer of 1988, when Andre Serafini and Russell Mofsky wanted to start a band. Andre played in a band, Chocolate Grasshopper, and Russell was playing with metal gods Cynic. They knew Addison Burns from the local skate scene and asked him to join. Omar Cuellar joined in on bass guitar. After a few months, Tony Rocha replaced Cuellar on bass, and Quit's first performance was on Labor Day weekend in 1988 for the Rock-A-Thon. Quit has had four full-time members since 1989: Andre Serafini on drums, Russell Mofsky on lead guitar, Addison Burns on lead vocals/rhythm guitar, and Tony Rocha on bass. Songs were written by band members, and they would work on the arrangements together. Quit released its first album, Earlier Thoughts, on Esync Records. Quit re-released Earlier Thoughts in 1996 on Rojo Records with two bonus tracks recorded live on the air from WLRN's Off the Beaten Path, an overnight punk radio program. Quit played consistently from 1988-1996.

Queers Undermining Israeli Terrorism

Queers Undermining Israeli Terrorism (QUIT!) is a gay San Francisco Bay Area political action group supporting "boycott, divestment & sanctions against Israel"; and opposing "Pinkwashing" of the "ethnic cleansing of the Palestinian people". It was founded in early 2001 by a member of LAGAI-Queer Insurrection and individuals formerly associated with DAGGER (Dykes & Gay Guys Emergency Response), which was active during the first Gulf War.

Goals

The group "supports divestment, the right of return for all Palestinians, immediate Israeli withdrawal from Palestinian territories and describes Zionism as racism."

The group opposes "Pinkwashing" (promoting through an appeal to "queer-friendliness") of the Israeli government and its allegedly anti-Palestinian policies.
