  The influence of variable geometry stators on the stage behavior is analyzed from both theoretical and experimental points of view. A theoretical analysis of the trajectory of some pressure-ratio lines in a loading-to-flow-coefficient diagram leads to the definition of a specific dimensionless parameter: the reduced by: 6. An off-design performance loss model was developed for variable-stator (pivoted vane), radial turbines through analytical modeling and experimental data analysis.

The area of the nozzle throat is a limiting factor in the performance of a turbocharger; many variable geometry turbocharger concepts allows for the alteration of this area. The effective area depends on the height of the passage (which can be altered in a sliding vane system) and the angle of the vanes (which can be altered in a pivoting vane Cited by: Full text of "NASA Technical Reports Server (NTRS) Bibliography of Lewis Research Center technical publications announced in " See other formats.

NASA Technical Reports Server (NTRS) Wasserbauer, C. A. This program calculates off design performance of radial inflow turbines. The program uses a one dimensional solution of flow conditions through the turbine along the main streamline. The loss model accounts for stator, rotor.
