Abstract
The axial flow turbine has an asymmetrical flow input, for example, at the first nozzle plate and which flow is attenuated towards an axi-symmetric flow by a baffle plate located between the first nozzle plate and the second stage. The baffle plate directs the flow towards a more symmetrical flow pattern before permitting the flow to pass through the second stage. Consequently, the long turbine blades in the later stages of the turbine respond to an attenuated asymmetrical flow rather than a larger asymmetrical flow which might induce vibrations or vibrations at the natural resonant frequency of the turbine blading which could break the turbine blades.
