Impulse Turbine - an overview | ScienceDirect Topics

The velocity diagram for a 50% reaction is symmetrical and, for the maximum utilization factor, the exit velocity (V 4) must be axial. Figure 9-14 shows a velocity diagram of a 50% reaction turbine and the effect on the utilization factor. From the diagram W 3 = V 4; the angles of both the stationary and rotating blades are identical. Therefore

Steam engine - Wikipedia

A steam engine is a heat engine that performs mechanical work using steam as its working fluid.The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force is transformed, by a connecting rod and flywheel, into rotational force for work.The term "steam engine" is generally applied only to reciprocating engines as just

Abstract: Reciprocating internal combustion enginesa subclass of heat enginescan be operated in the four- and two-stroke cycles.In each case, the engine may be equipped with either a spark-ignited (SI) or a compression-ignited (CI) combustion system. A number of other engine classifications are possible, based on engine mobility, application, fuel, configuration, and other design parameters.
