Abstract: The article is devoted to the optimization of annular diffusers of radial-axial turbines of small-sized gas turbine engines. It shows the results of verification of the used mathematical models for calculating the flow using experimental performance charts for annular diffusers. The results of the geometry optimization of the developed diffuser are presented. The final part of the article covers the results of the optimization of the diffuser geometry by the swirl angle of the inlet flow. As a result, a highly efficient diffuser was designed for a 50 kW microturbine under development.
Keywords: Diffuser, Microturbine, Mathematical Model, Swirl Angle.
