Characterization of Distributed Combustion of Reformed Methanol Blends in a Model Gas Turbine Combustor

Combustion of Reformed Gas and Liquid Fuel in Crgt Combustor

Original scientific paper Numerical simulations of four combustion processes in a dual-fuel combustor of chemically recuperated gas turbine (CRGT) were carried out in this work. The fuels in the four combustion processes were liquid fuel, liquid fuel + steam, liquid fuel + reformed gas and reformed gas, respectively. The mathematical models adopted for different fuels combustion consist of real...

Numerical Simulation of a Confined Swirling Flow in a Model Gas Turbine Combustor

Acoustic Behavior of a Partially-Premixed Gas Turbine Model Combustor

Combustion instabilities in gas turbine engines often give rise to acoustic resonances. These resonances occur as manifestations of different acoustic modes, of which a single or multiple modes may be present. In this work, the acoustic behavior of a model gas turbine combustor, developed at DLR Stuttgart by Meier, was investigated using both syn(thetic) gas and standard hydrocarbon fuels. Syng...

Large Eddy Simulation of a Gas Turbine Model Combustor

The current design of gas-turbine (GT) systems is driven by the need for increased powerdensities, improved fuel-efficiencies, and reduced life cycle costs and environmental impact. Computational techniques have the potential for providing valuable information for the design of GT combustion systems, if adequate models are available. Over recent years, remarkable progress has been made in the d...
