Pneumatic motor low engine temperatures. The Pneumatic Quasiturbine engine is a compressed air pistonless rotary engine using a rhomboidal-shaped rotor whose sides are hinged at the vertices. The Quasiturbine has demonstrated as a pneumatic engine using stored compressed air It can also take advantage of the energy amplification possible from using available external heat, such as solar energy. The Quasiturbine rotates from pressure as low as 0.1 atm (1.47psi). Since the Quasiturbine is a pure expansion engine, while the Wankel and most other rotary engines are not, it is well-suited as a compressed fluid engine, air engine or air motor. Armando Regusci's
Losses in steam turbines Losses in steam turbines Any turbomachine extracts energy from high-pressure steam and converts it into shaft work. The total energy content available in steam supplied to the steam turbine is not completely recovered in the form of mechanical energy. There are certain losses in energy of steam which occur inside a turbine... In practice the flow of steam through nozzle is not isentropic, but accompanied with losses which decrease the kinetic energy of steam coming out of the nozzle. The decrease in kinetic energy is due to the following reasons Steam leaves the boiler and reaches the condenser after passing
