Hele-Shaw flow is defined as flow taking place between two parallel flat plates separated by a narrow gap satisfying certain conditions, named after Henry Selby Hele-Shaw, who studied the problem in 1898. [1] [2] Various problems in fluid mechanics can be approximated to Hele-Shaw flows and thus the research of these flows is of importance ...
This photo of Henry Selby Hele-Shaw appeared in Page's Magazine, August 1902.. Henry Selby Hele-Shaw FRS [1] (1854–1941) was an English mechanical and automobile engineer. He was the inventor of the variable-pitch propeller, which contributed to British success in the Battle of Britain in 1940, [citation needed] and he experimented with flows through thin cells.
The simplest case of the instability arises at a planar interface within a porous medium or Hele-Shaw cell, and was treated by Saffman and Taylor [1] but also earlier by other authors. [6] A fluid of viscosity μ 1 {\displaystyle \mu _{1}} is driven in the x {\displaystyle x} -direction into another fluid of viscosity μ 2 {\displaystyle \mu ...
Clay is composed of closely packed particles of silica and other minerals, and water flows through the narrow spaces between these particles just as it would through a narrow glass tube. Any combination of an electrolyte (a fluid containing dissolved ions) and an insulating solid would generate electro-osmotic flow, though for water/ silica the ...
This list of citizen science projects involves projects that engage all age groups. There are projects specifically aimed at the younger age demographic like iTechExplorers [ 7 ] which was created by a 14 year old in the UK to assess the effects of bedtime technology on the body's circadian rhythm and can be completed in a classroom setting.
This is a list of experiments at CERN's Large Hadron Collider (LHC). The LHC is the most energetic particle collider in the world, and is used to test the accuracy of the Standard Model, and to look for physics beyond the Standard Model such as supersymmetry, extra dimensions, and others.
Installation of the Gargamelle chamber body. Placement of the chamber in the oblong shaped magnet coils. The domain of neutrino physics was in rapid expansion in the 60's. . Neutrino experiments using bubble chambers were already running at the first synchrotron at CERN, the PS, and the question of the next generation of bubble chambers had been on the agenda for some ti
"Large scale simulation experiments were begun by the U.S. Army Corps of Engineers in 1953 for reservoir management on the main stem of the Missouri River". This, [ 5 ] and other early work that dealt with the River Nile [ 6 ] [ 7 ] and the Columbia River [ 8 ] are discussed, in a wider context, in a book published by the Harvard Water ...
