Aerodynamics Of Turbines
The transformation between work and other forms of energy is accomplished in turbomachinery. The ability of a turbine to produce work when handling a compressible fluid and when taking either its axial or radial configuration is presented for the user of the equipment rather than the designer or research worker. The basic conservation principles of mass, linear momentum, energy, and angular momentum in their steady, one-dimensional form are summarized; the figures of merit of turbine stage performance including efficiency, reaction and reheat are defined and interrelated. Correlation of losses with performance parameters is presented first for the over-all stage. Then the Soderberg correlation is provided for handling the axial stage, component by component, and the Benson correlation is introduced for use with a radial stage. An example lists all of the parameters and flow conditions which can be predicted for a prospective design or evaluated for an existing unit of hardware.
