The figure shows one such ideal expansion fan. A supersonic expansion fan, technically known as Prandtl–Meyer expansion fan, a two-dimensional simple wave, is a centered expansion process that occurs when a supersonic flow turns around a convex corner. The fan consists of an infinite number of Mach waves, diverging from a sharp corner. When a ...
In thermodynamics, the Joule–Thomson effect (also known as the Joule–Kelvin effect or Kelvin–Joule effect) describes the temperature change of a real gas or liquid (as differentiated from an ideal gas) when it is expanding; typically caused by the pressure loss from flow through a valve or porous plug while keeping it insulated so that no heat is exchanged with the environment.
A number of materials contract on heating within certain temperature ranges; this is usually called negative thermal expansion, rather than "thermal contraction".For example, the coefficient of thermal expansion of water drops to zero as it is cooled to 3.983 °C (39.169 °F) and then becomes negative below this temperature; this means that water has a maximum density at this temperature, and ...
The CAGE Distance Framework identifies Cultural, Administrative, Geographic and Economic differences or distances between countries that companies should address when crafting international strategies. [1]
Temperature gradients, thermal expansion or contraction and thermal shocks are things that can lead to thermal stress. This type of stress is highly dependent on the thermal expansion coefficient which varies from material to material. In general, the greater the temperature change, the higher the level of stress that can occur.
The fortress Ordensburg Marienburg in Malbork, founded in 1274, the world's largest brick castle and the Teutonic Order's headquarters on the river Nogat.. The medieval German Ostsiedlung (literally Settling eastwards), also known as the German eastward expansion or East colonization refers to the expansion of German culture, language, states, and settlements to vast regions of Northeastern ...
The Joule expansion (a subset of free expansion) is an irreversible process in thermodynamics in which a volume of gas is kept in one side of a thermally isolated container (via a small partition), with the other side of the container being evacuated. The partition between the two parts of the container is then opened, and the gas fills the ...
The main effect of the presence flash-gas in the liquid piping is the net loss of refrigeration capacity. [2] In general terms this is produced in two ways. First, the expansion valve usually doesn't work properly if injecting a gas-liquid mixture such as refrigerant with flash-gas presence.
