Old Problems, New Techniques: Using Computational Fluid Dynamics to Find the Missing Flow

摘要

Flow rate is usually the most difficult and expensive measurement for a hydroturbine efficiency test. The Tennessee Valley Authority (TVA) has used current meter racks extensively to perform this measurement. The technique is a cost-effective method that meets the uncertainty requirements specified by the ASME test code, PTC 18 (ASME, 1992).
