Diffuser efficiency develop
WebOct 1, 2024 · 1. Introduction. Diffuser-augmented horizontal-axis wind turbines (DAWTs) have been extensively studied, because the diffuser increases the velocity at the turbine … WebDec 31, 2009 · The test flow passage is a straight, annular diffuser with three sets of struts. At the end of Phase 1, the ability of strutlets to keep flow attached to struts was demonstrated, but the strutlet drag was too high for a net efficiency advantage. An independently sponsored followup project did develop a highly-modified low-drag strutlet.
