description: The aim of this work is to study the effect of changes in the length of the conical diffuser sleeve relative to the basic design of the GTU V84.3A diffuser, taking into account the use of reverse flow swirling in the last stage. The comparison is carried out according to such parameters as the pressure recovery factor and the normalized value of the efficiency gain. blockThe theoretical aspects of the layout and designs of the âlast stage-diffuserâ blocks of stationary gas turbines of large unit power are considered.Numerical modeling of 3 options for calculating the outlet duct of a gas turbine unit: the basic version of the outlet duct, the option with an extended bushing and the option with a long bushing has been carried out.The analysis of the obtained results of the numerical experiment, the validation of the integral aerodynamic parameters based on the results of the experimental study of the outlet duct of the basic design, and also the conclusion about the expediency of further research of the non-standard version of the design of the outlet duct, both numerical and experimental, is made.
