DIFFUSER OF A THERMAL ENERGY MACHINE AND THERMAL ENERGY MACHINE

摘要

The invention relates to a diffuser (1) of a thermal energy machine (3), in particular of a gas turbine (5), comprising a diffuser inlet (20), a diffuser outlet (22), and a plurality of air-guiding elements (23), wherein an air mass flow enters the diffuser (1) through the diffuser inlet (20), and wherein the air mass flow that has entered the diffuser (1) exits the diffuser (1) through the diffuser outlet (22) and flows off as a plurality of partial air mass flows (24) by means of the air-guiding elements (23), wherein at least two immediately adjacent air-guiding elements (23) of the plurality of air-guiding elements (23) are designed in such a way that the flow-off angles (αn) thereof with respect to the circumferential surface (32) formed by the outlet opening (31) of the diffuser outlet (22) extending circumferentially in the circumferential direction (25) differ from each other.
