Abstract: Internal cooling air systems of turbomachines contain various fluid flow components, i.e., rotating holes, tapping configurations, coverplates, labyrinth seals, etc., for which only the basic ...

Abstract: The flow field in a preswirled cooling air supply to a turbine rotor has been investigated by means of CFD simulations. Coefficients for system efficiency are derived. The influences of various ...

Abstract: A kite-powered pump which employs a kite to convert wind energy into potential energy of water has been studied to determine its performance characteristics and see if the steady-state operation ...

Abstract: The friction losses of rotating disks in turbomachines are often increased by protruding bolt heads and surface imperfections, especially at the rim. This can significantly influence the heat ...
