- Gas expansion is the process by which gas increases in volume as it moves from a region of higher pressure to a region of lower pressure. This expansion occurs because of constant motion of gas particles and they tend to spread out to fill the available space. When the pressure on a gas is reduced, the gas molecules move farther apart, resulting in an increase in volume.
Applications :
Gas Turbines: Gas expansion plays a central role in gas turbine engines, such as those used in aircraft propulsion and power generation.
Spray Cans: When the valve is opened, the gas rapidly expands, forcing the contents out of the can in a fine spray.
Refrigeration and Air Conditioning: Gas expansion is crucial in refrigeration and air conditioning systems, as a refrigerant gas undergoes controlled expansion, often in an evaporator coil.
Internal Combustion Engines: In the power stroke of a four-stroke engine, a mixture of fuel and air is ignited, causing rapid expansion of gases within the combustion chamber.
