Gas atomization
Gas atomization is a powder production process in which high-pressure jets of neutral gas, typically nitrogen or argon, break molten metal into droplets that solidify into spherical powder.
Gas balloon
A gas balloon, also known as a Charlière or La charliere, is a lighter-than-air aircraft lifted by helium or hydrogen, first flown with a person aboard by Jacques Charles in 1783.
Gas barrier film
A gas barrier film is a thin polymer or composite sheet engineered to slow the passage of oxygen, water vapor, and other gases, mainly in food packaging and electronics.
Gas bearing
A gas bearing supports a rotating shaft on a film of gas, usually air, used in high-speed turbomachinery and precision instruments where oil is unwanted.
Gas block
A gas block is the barrel-mounted component of a gas-operated firearm that captures propellant gas at the gas port and directs it to a gas tube or piston.
Gas centrifuge
A gas centrifuge is a device that separates uranium isotopes by spinning UF6 gas at very high speed in a vertical rotor, and it is the only process used for commercial uranium enrichment worldwide since 2013.
Gas chromatography–mass spectrometry
Gas chromatography–mass spectrometry, also known as GC-MS, is an analytical technique coupling a gas chromatograph to a mass spectrometer to identify volatile compounds, first demonstrated in 1955–56.
Gas cylinder
A gas cylinder, also called a compressed gas cylinder or gas canister, is a pressure vessel that stores gases such as oxygen, propane, and acetylene at high pressure.
Gas diffusion electrode
A gas diffusion electrode (GDE) is a porous composite electrode bringing gas, electrolyte, and catalyst into contact at three-phase interfaces, used in fuel cells and CO2 reduction.
Gas discharge tube
A gas discharge tube (GDT), also called a gas tube surge arrester, is a surge protection component that acts as an open circuit until voltage exceeds its sparkover voltage.
Gas Distribution s.r.o.
Gas Distribution s.r.o. is a Czech natural gas distributor serving the South Bohemian Region and parts of the Vysočina Region, owned by GasNet in the ČEZ group.
Gas flare
A gas flare, also called a flare stack, is a device that burns waste gases at oil production sites, flaring about 151 billion cubic meters globally in 2022.
Gas holder
A gas holder, or gasometer, is a large container that stores town gas or natural gas at near atmospheric pressure, its volume changing as gas is added or withdrawn.
Gas kinetic scheme
The gas kinetic scheme (GKS) is a finite-volume computational fluid dynamics method that computes numerical fluxes from the time-evolution solution of the Boltzmann equation rather than a Riemann solver.
Gas lift
Gas lift is an artificial lift method for oil and gas wells in which high-pressure gas is injected into the tubing to lighten the fluid column.
Gas lighting
Gas lighting, also called gas lamp lighting, is the production of artificial light by burning gaseous fuel, historically coal gas, first demonstrated on London's Pall Mall in 1807.
Gas mask
A gas mask is a tight-fitting full-face respirator that draws inhaled air through a filter removing toxic gases and particles, developed after poison gas first appeared in 1915.
Gas metal arc welding
Gas metal arc welding (GMAW), commonly called MIG welding, is an arc welding process in which a continuously fed wire electrode and shielding gas melt the joint.
Gas porosity
Gas porosity is a casting defect in which gas bubbles, usually dissolved hydrogen in molten aluminum, become trapped during solidification and form rounded voids that reduce strength and fatigue life.
Gas space heater
A gas space heater burns natural gas or LPG to warm a single room or, in ducted form, a whole house, as distinct from a central furnace.
Gas Street Basin
Gas Street Basin is a canal basin in central Birmingham where the Worcester & Birmingham Canal meets the Birmingham Canal Navigations Main Line, once separated by the Worcester Bar.
Gas Transmission Northwest
Gas Transmission Northwest is a TC Energy-owned interstate natural gas pipeline, operating since 1961, that carries Canadian and Rocky Mountain gas through Washington and Oregon toward California.
Gas Transmission System Operator of Ukraine
Gas Transmission System Operator of Ukraine (Оператор ГТС України, GTSOU) is the independent operator of Ukraine's main gas pipelines, certified in December 2019 under the EU's ISO unbundling model.
Gas tube
A gas tube is a slender conduit in a gas-operated firearm that carries propellant gas from the barrel to the bolt carrier, cycling the action.
Gas tungsten arc welding
Gas tungsten arc welding, or TIG welding, is an arc welding process using a non-consumable tungsten electrode and an inert gas shield, valued for precision on thin materials.
Gas turbine
A gas turbine, also called a combustion turbine, is a heat engine operating on the Brayton cycle that drives generators, propels aircraft, and powers ships.
Gas turbine locomotive
A gas turbine locomotive is a locomotive powered by a gas turbine instead of a diesel engine, most often driving a generator that feeds electric traction motors.
Gas Turbine-Modular Helium Reactor
The Gas Turbine-Modular Helium Reactor (GT-MHR) is a helium-cooled high-temperature reactor design, developed by General Atomics and OKBM in Russia, that drives a gas turbine directly instead of producing steam.
Gas welding
Gas welding is a family of welding processes in which a fuel gas burned with oxygen produces a flame that melts metal edges so they fuse into a joint.
Gas-cooled fast reactor
A gas-cooled fast reactor is a proposed nuclear reactor combining a fast neutron spectrum with high-temperature helium cooling and a closed fuel cycle; it is one of six Generation IV systems.
