Through-flow calculation methods
Abstract
The place of the through-flow calculation in the design of turbomachinery components is indicated and the interaction with other calculations in the procedure is discussed. The equations of motion for a quasi-three dimensional through-flow analysis were derived, using a passage-averaging technique. The relationship with other through-flow models is considered. The streamline curvature method of solution of these equations is presented. The radial equilibrium equation used in the method is derived and details of the numerical solution are given. Extensions to the method and the basic through-flow model, including annulus wall boundary layers and cooling flows, are treated. The matrix method, finite element and time-marching methods are mentioned and the relationships between the methods are indicated.
