Experimental model for evaluation of the aerodynamic tract influence

This article describes an experimental model that consists of an annular diffuser with a subsequent conical diffuser to investigate the effect of aerodynamic traces produced by the rotation of the turbine. The model uses a special ring-simulator with adjustable speed, with a spoke diameter of 5 mm to create a phenomenon of oscillation of the turbine rotor. The purpose of this study is to analyze the effect of aerodynamic tracks on the flow structure in the interturbine GTE transition channel.
