On the Treatment of Body Forces in the Radial Equilibrium Equation of Turbomachinery (Ueber die Behandlung von Feldkraeften in der Gleichung des Radialen Gleichgewichts in Turbomaschinen).

Abstract A derivation of the axisymmetric 'radial equilibrium equation' of turbomachinery is presented. The derivation employs spatially distributed body force fields to account for the effects of blade shape and of streamwise entropy gradients within the flow field. The derivation is aimed at a formulation convenient for use with streamline curvature computing procedures. Computing stations may be non-radial and the analysis is suitable for radial as well as axial turbomachinery. Finally, it is shown how airfoil gas bending forces may be obtained from the body force fields and how this result may be further used to determine blade surface velocities in some instances.
