Which is the radial flow turbine?

A radial flow turbine is a turbine where the working fluid flows radially relative to the shaft. Therefore, this is the primary difference between axial and radial turbines due to the direction of the fluid flow through the components. An example of a radial inflow type of turbine is the Francis turbine.

What is radial flow gas turbine?

A radial turbine is a turbine in which the flow of the working fluid is radial to the shaft. The difference between axial and radial turbines consists in the way the fluid flows through the components (compressor and turbine).

Is Kaplan turbine a radial flow reaction turbine?

The Kaplan turbine is an inward flow reaction turbine, which means that the working fluid changes pressure as it moves through the turbine and gives up its energy. Power is recovered from both the hydrostatic head and from the kinetic energy of the flowing water.

What are four types of turbine seals?

Labyrinth mated with shaft serration’s or shaft seal strips. Water seals where a shaft runner acts as a pump to create a ring of water around the shaft. Use only treated water to avoid shaft pitting. Stuffing box using woven or soft packing rings that are compressed with a gland to prevent leakage along the shaft.

What is the difference between axial and radial flow?

“Axial” refers to the direction of flow produced by the impeller. Similar to the axial flow turbine, the term “radial” describes the flow of liquid resulting from the impeller. The radial turbine blades are welded to the hub with the blade surfaces parallel to the shaft.

What is radial flow?

Definition of radial-flow : having the working fluid flowing mainly along the radii of rotation a radial-flow turbine — compare axial-flow.

What is the difference between Francis Pelton and Kaplan turbine?

The basic difference between Pelton, Francis and Kaplan Turbines is explained in this article. Francis Turbine is an inward flow reaction turbine. Kaplan turbine is a propeller type reaction turbine. The Kaplan Turbine uses both kinetic and potential energy, which then is converted into mechanical energy.

What is mean by inward flow in radial turbines?

The radial-inflow turbine, or inward- flow radial turbine, has been in use for many years. Basically, a centrifugal compressor with reversed flow and opposite rotation , the inward-flow radial turbine is used for smaller loads and over a smaller operational range than the axial turbine.

What is radial and axial flow?

Jump to navigation Jump to search. A radial turbine is a turbine in which the flow of the working fluid is radial to the shaft. The difference between axial and radial turbines consists in the way the fluid flows through the components (compressor and turbine).

What is an axial flow turbine?

An axial turbine is a turbine in which the flow of the working fluid is parallel to the shaft, as opposed to radial turbines, where the fluid runs around a shaft, as in a watermill. An axial turbine has similar construction as an axial compressor, but it operates in the reverse, converting flow of the fluid into rotating mechanical energy.

What are turbine flow meters?

Turbine flow meters use the mechanical energy of the liquid to rotate a rotor in the flow stream. The rotational speed of the rotor is directly proportional to the velocity of the fluid travelling through the meter. These meters are used in multiple industries to reliably measure the velocity of a variety of liquids, gases and vapors.
