Experimental study of vortex-flame interaction in a gas turbine model combustor

Influence of Thermal Radiation Models on Prediction of Reactive Swirling Methane/Air Flame in a Model Gas Turbine Combustor

 A numerical simulation of reactive swirling methane/air non-premixed flame in a new three-dimensional model combustion chamber is carried out to assess the performance of two thermal radiation models, namely, the Discrete Transfer Radiation Model and the P-1 Model. A Finite Volume staggered grid approach is employed to solve the governing equations.The second-order upwind scheme is applied for...

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

CFD Insight of the Flow Dynamics and Velocity Fields in a Gas Turbine Combustor with a Swirl Flame

The computational fluid dynamics (CFD) simulations of gas turbine combustor were performed for CH4<span st...

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...
