The rebels tunnelled out of a maximum security jail see also wind tunnel. Horizontal or nearly horizontal underground or underwater passageway. Tunnels are used for mining, as passageways for trains and motor vehicles, for diverting rivers around damsites, for housing underground installations such as power plants, and for conducting water. Ancient civilizations used tunnels to carry water for irrigation and drinking, and in the 22nd century BC the Babylonians built a tunnel for pedestrian traffic under the Euphrates River. The Romans built aqueduct tunnels through mountains by heating the rock face with fire and rapidly cooling it with water, causing the rock to crack. The introduction of gunpowder blasting in the 17th century marked a great advance in solid-rock excavation. For softer soils, excavation is accomplished using devices such as the tunneling mole, with its rotating wheel that continuously excavates material and loads it onto a conveyor belt. Railroad transportation in the 19th-20th century led to a tremendous expansion in the number and length of tunnels. Brick and stone were used for support in early tunnels, but in modern tunneling steel is generally used until a concrete lining can be installed. A common method of lining involves spraying shotcrete onto the tunnel crown immediately after excavation. carpal tunnel syndrome Channel Tunnel wind tunnel; To make an opening, or a passageway, through or under; as, to tunnel a mountain; to tunnel a river; Loosely applied to any horizontal shaft but a tunnel must be open to the air at both ends; an adit is open to the air at one end, if it were continued completely through a hill, it would be a tunnel; move through by or as by digging; "burrow through the forest"; 1 A structure, installation, or facility incorporating apparatus to simulate flight conditions in one way or another, specially designed for testing or experimenting with power plants, or with aircraft, rockets, or other aerodynamically designed bodies, engine installations, or models; specifically, a wind tunnel; force a way through; a tunnel used to carry a roadway through a mountain or under a river instead of around or over those obstacles Tunnels can be very expensive to construct and maintain due to drilling and ventilation requirements Generally, most tunnels are located in mountainous or hilly regions, and examples include the Fort Pitt Tunnel (Interstate 279) in Pittsburgh and the Waldo Tunnel (U S 101) north of San Francisco; An artificial passage or archway for conducting canals or railroads under elevated ground, for the formation of roads under rivers or canals, and the construction of sewers, drains, and the like; {f} dig a tubular passage, create a tunnel; A secure communication path between two peers, such as a client and a router; When a canal passes through the ground (e g under a hill); A secure encrypted connection between two points through a public or third-party network; a passageway through or under something, usually underground (especially one for trains or cars); "the tunnel reduced congestion at that intersection"

tunneling: A VPN can be created by using "tunneling " Tunneling is a technology that allows a network transport protocol to carry information for other protocols within its own packets For example, IPX data packets can be encapsulated in IP packets for transport across the Internet, which isn't normally possible The packets are delivered unmodified to a remote device that has been setup to handle them The packets maybe secured using data encryption, authentication or integrity functions
tunneling: v. or barrier penetration In physics, the passage of a particle through a seemingly impassable energy barrier. Though a particle's energy may be too low to surmount a barrier in classical physics, the particle may still cross the barrier as a consequence of its quantum-mechanical wave properties. An important application of this phenomenon is in the operation of the scanning tunneling microscope
tunneling: An important concept in the design of many kinds of networks: taking some protocol-family's ability to move packets from user to user, or to open virtual-circuits between users, and use this as if it were a data-link protocol to run another protocol family's upper layers (or even the same protocol family's upper layers) Examples: running TCP/IP over AppleTalk instead of something like Ethernet; running AppleTalk over DECNet instead of something like Localtalk or Ethernet

wind tunnel: tunnel (or a tubular room or structure) where wind is created to test parts of aircrafts or a completer aircraft
wind tunnel: A wind tunnel is a room or passage through which air can be made to flow at controlled speeds. Wind tunnels are used to test new equipment or machinery, especially cars and aeroplanes. A chamber through which air is forced at controlled velocities in order to study the effects of aerodynamic flow around airfoils, scale models, or other objects. a large enclosed passage where engineers test aircraft etc by forcing air past them. Device for producing a controlled stream of air to study the effects on objects such as aircraft moving through air or the effects of moving air on models of stationary objects such as buildings. Applications of wind-tunnel research range from testing of airframes (the structures of aircraft and spacecraft) to research on the boundary layer, turbulence, drag, and lift. Measurements of air pressure and other characteristics at many points on the model yield information about how the total wind load is distributed. In addition to testing the effects of wind on aircraft and spacecraft, studies in wind tunnels have been used to solve design problems in automobiles, boats, trains, bridges, and buildings. See also aerodynamics
