In these slides we will cover the following topic in detail so for the complete description download the given slides.
A device that exchanges energy with the fluid, using continuously flowing fluid and rotating blades.
e.g Aircraft Engine, Wind Turbine.
- If the device extract energy from fluid generally called as turbine.
- If the device deliver energy to fluid generally called as pump.
turbo machinery is the generic name of all these machines.
Nozzles?
A nozzle is a duct of smoothly varying cross section area in which a steadily flowing fluid can be made to accelerate by a pressure drop along the duct. Nozzles are used in steam turbines, in rockets,in injector and ejector etc.
Diffuser ?
When a fluid is decelerated in a duct causing a rise in pressure along the steam. e.g centrifugal pump etc.
