4 Frequently Asked Questions about “Generator air shroud design performance - Inala Strategic Solar”
Does shroud design affect turbine efficiency?
In the last two decades a lot of papers regarding the effect of the shroud design on the flow structure, tip clearance losses and turbine efficiency have been issued.
Why do turbine blades have shrouds?
Last blades of heavy-duty gas and steam turbines have shrouds to avoid dangerous resonance frequency. In this paper, a numerical investigation of the flow structure around full and partial shrouds with various geometries and the effect of the various shrouds on the turbine stage efficiency are carried out.
Can a blade shroud be modified?
The design modification of a typical blade shroud was the subject of a major design project in the course “Finite Element Applications in Mechanical Design,” ME 4603, at the University of Texas at San Antonio. A study of currently used shroud configurations was conducted, and several modifications were investigated.
Does a partial shroud reduce aerodynamic efficiency?
Porreca et al. (2007) studied three variants of shroud design: full shroud, partial shroud and enhanced partial shroud. The investigation showed that the use of partial shroud decreases aerodynamic efficiency by 1% in comparison with the full shroud case and optimized partial shroud decreases aerodynamic efficiency by 0.5%.
