For water-cooled engines on aircraft and surface vehicles, waste heat is transferred from a closed loop of water pumped through the engine to the surrounding atmosphere by a radiator. Water has a higher heat capacity than air, and can thus move heat more quickly away from the engine, but a radiator and pumping system add weight, complexity, and ...
The result was deep pits that could form and penetrate the engine head in a matter of hours when the engine was running at high load and high speed. These effects could largely be avoided by the use of organic corrosion inhibitors or (preferably) by designing the engine head in such a way as to avoid certain cavitation inducing conditions.
a radiator, consisting of many small tubes equipped with a honeycomb of fins to dissipate heat rapidly, that receives and cools hot liquid from the engine; a water pump, usually of the centrifugal type, to circulate the coolant through the system; a thermostat to control temperature by varying the amount of coolant going to the radiator;
"Like Water for Octane," an episode of The Lone Gunmen, [53] is based on a "water-powered" car that character Melvin Frohike saw with his own eyes back in 1962. [54] The Water Engine, a David Mamet play made into a television film in 1994, tells the story of Charles Lang inventing an engine that runs using water for fuel. The plot centers on ...
Notable engine with water fuel injection: BMW 801, Daimler-Benz DB 605, Junkers Jumo 213. When used in a turbine engine, the effects are similar, except that normally preventing detonation is not the primary goal. Water is normally injected either at the compressor inlet or in the diffuser just before the combustion chambers.
In 1912, Humber produced a light car called the Humberette with a Humber-made V-twin side-valve engine of 998cc. The engine had a directly attached clutch, 3-speed gearbox and prop shaft output to a rear differential. A water cooled version of this engine was made available in 1914, but WW1 ended Humberette production in 1915. [25]
Light water reactors, both boiling water and pressurised water reactors the most common type, use ordinary (light) water. Some designs, e.g. CANDU reactor, use both types; heavy water in the nonpressurized calandria tank as the moderator and a supplementary coolant, and light water as the primary heat transfer fluid.
Boiling water creating steam in an electric kettle. Steam's capacity to transfer heat is also used in the home: for cooking vegetables, steam cleaning of fabric, carpets and flooring, and for heating buildings. In each case, water is heated in a boiler, and the steam carries the energy to a target object.
