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...

Parametric Modelling System of Gas Turbine Combustor

Original scientific paper In the numerical simulation research of gas turbine combustor, there are plenty repetitive operations such as modelling and meshing. Parametric design idea is about simplifying it. This paper establishes a parametric modelling system of gas turbine combustor, mainly for the flame tube components, which includes parametric modelling and simple mesh generation. Taking a ...

critical period effects in foreign language learning:the influence of maturational state on the acquisition of reading,writing, and grammar in english as a foreign language

since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
