Abstract

The subject of this study is the simulation of low-frequency transients (such as acceleration, deceleration) of different open cycle gas turbine types. Special attention is paid to the correct calculation of the effects of heat transfer between process gas and solid structure. Correcting equations for these effects are developed and the transient properties of each component are then evolved from the static ones with these equations. It is shown that the heat transfer effects alter significantly the surge margin of the compressor. Simulation model includes intercooler and recuperation. The programming language is CSMP.Copyright © 1984 by ASME
