change in direction of flow of steam, it is essential to draw velocity diagram that shows how velocity of the steam varies during its passage through the blades. Velocity is vector quantity as it has magnitude and direction. So we can represent velocity by a …
Compounding of steam turbines - Wikipedia
Fig-7: Velocity Diagram of Pressure Compounded Reaction turbine. The velocity diagram given in figure 7 gives a detail about the various components of steam velocity and blade velocity (symbols have the same meaning as above).
Steam Turbine | Steam Turbine Velocity Diagram
Let us draw the steam turbine velocity diagram.Assume, it creates at an angle a to the tangent of the wheel with a velocity V 1 which is the absolute velocity of steam. This absolute velocity V 1 has two components.
Velocity diagram for Impulse Turbine Let:- Vb = linear velocity of moving blade V1= absolute velocity of steam at inlet to moving blade; i. e. exit velocity of nozzle
How to draw velocity diagram (Part 1) - de Laval Impulse steam turbine

In impulse turbine velocity (or kinetic energy) of steam increases in nozzle while this work is to be done by fixed blades in the reaction turbine. Compounding is to be done for impulse turbines to increase their efficiency while no compounding is necessary in reaction turbine.
12 . 6 Velocity Triangles for an Axial Flow Turbine Stage
The appropriate velocity triangles are shown in Figure 12.9, where again the axial velocity was assumed to be constant for purposes of illustration. As we did for the compressor, we can write the Euler Turbine Equation in terms of useful design variables:
The velocity-compounded impulse turbine was first proposed by C.G. Curtis to solve the problems of a single-stage impulse turbine for use with high pressure and temperature steam. The Curtis stage turbine, as it came to be called, is composed of one stage of nozzles as the single-stage turbine, followed by two rows of moving blades instead of one.
