Method of analysis of secondary air circuits in gas turbine plants

摘要

A method of analysis of secondary-air circuits in gas-turbine plants includes the step of defining an equivalent fluid-dynamic network (25) of a secondary-air circuit (7) of a gas-turbine plant (5). The equivalent fluid-dynamic network (25) includes a plurality of elements (18, 20), organized in branches (21) and connected to nodes (22). For at least one element (18, 20) of the secondary-air circuit (7) a principal component of flow (V P ) and at least one auxiliary component of flow (V A1 , V A2 ) are calculated.
