Run time Assessment for Gas Turbine Performance Simulation

Henrique Gazzetta Junior, Cleverson Bringhenti, João Roberto Barbosa, Jesuíno Takashi Tomita


This article describes the run time characteristics of a gas turbine performance simulation using different solvers and components off-design performance database formats. Two different nonlinear systems of equation solvers, Newton-Raphson’s and Broyden’s, and two different formats of compressor and turbine off-design performance database (maps),tabulated values and fi tted surface equations, were compared. Based on the results it is then possible to trade off and select the most appropriate combination of solver and component map type for the gas turbine performance simulation for real-time application.
