Compressible Flow and Work Transfer in Turbine Blading

Abstract

In the previous programme we have seen how we may calculate the amount of work that may be obtained from steam delivered to a turbine and expanded to a given pressure. This is one example of a work interaction between a fluid in motion and a rotating wheel with blades. Other examples are a gas turbine, and a gas or air compressor. We now need to get an insight into how this work interaction is achieved in practice.
