Web13 apr. 2024 · A new heat engine with no moving parts is as efficient as a steam turbine. The design could someday enable a fully decarbonized power grid, researchers say. … WebAn air powered engine will generate the most velocity with a converging nozzle such as is described on the three rotor turbine below. However, steam is heated and can expand. In that case, providing more volume just before injection to the rotor blades converts as much heat as possible to velocity.
WebSince Carnot’s principle states that no engine can be more efficient than a reversible engine ( a Carnot heat engine) operating between the same high temperature and low-temperature reservoirs, a gas turbine based on the Brayton cycle must have lower efficiency than the Carnot efficiency.
