Journal ArticleDOI
Design performance analysis of pressurized solid oxide fuel cell/gas turbine hybrid systems considering temperature constraints
TL;DR: In this paper, the effect of matching between the fuel cell temperature and the turbine inlet temperature on the performance of hybrid power systems combining a pressurized solid oxide fuel cell (SOFC) and a gas turbine (GT) was analyzed.
Journal ArticleDOI
Performance prediction of axial flow compressors using stage characteristics and simultaneous calculation of interstage parameters
TL;DR: In this paper, a new method for predicting performance of multistage axial flow compressors is proposed that utilizes stage performance curves, which differs from the conventional sequential stage-stacking method in that it employs simultaneous calculation of all interstage variables (temperature, pressure and flow velocity).
Journal ArticleDOI
Exergy-based performance analysis of the heavy-duty gas turbine in part-load operating conditions
TL;DR: In this paper, the authors describe details of exergy-based performance characteristics of a heavy-duty gas turbine, 150MW-class GE 7F model and show that a chemical reaction in the combustor of which the exergy destruction ratio is 28.3% at full-load is one of the major sources of exery destructions in the gas turbine.
Journal ArticleDOI
Dynamic Simulation of Full Startup Procedure of Heavy-Duty Gas Turbines
TL;DR: In this article, a simulation program for transient analysis of the startup procedure of heavy duty gas turbines for power generation has been constructed, where unsteady one-dimensional conservation equations are employed and equation sets are solved numerically using a fully implicit method.
