Abstract: The Tennessee Valley Authority and Voith Hydro, Inc., are conducting a joint research project to study the effects of air admission on hydraulic turbines. Francis turbine models, homologous to TVA's Norris project, of both the existing turbine and a new proposed turbine are being tested with air admission at various individual and combinations of locations. Performance and oxygen uptake data are being obtained to determine the most efficient of the proposed air admission configurations. This paper discusses some of the problems dealt with in the initial stages of testing.
