Fiber-coupled phosphor thermometry for wall temperature measurements in a full-scale hydrogen gas turbine combustor

چکیده

Abstract Online wall temperatures were measured with fiber-coupled phosphor thermometry in a full-scale gas turbine combustor. The combustor was operated natural and up to 100 vol% hydrogen at engine-relevant conditions. Two phosphors tested for this application, namely YAG:Dy YAG:Tm;Li. Although YAG:Tm;Li seemed be the most promising it turned out incompatible used setup due strong interfering signal generated by laser fiber setup. A strategy compensate interferences from flame emissions during operation developed. With possible obtain single-shot temperature measurements 15 Hz precision of 2–7 K 1 s average.

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 ...

Multi-Intensity-Layer PIV application to a Gas Turbine Combustor

The new technique ‘Multi-Intensity-Layer PIV’ was applied to a gas turbine combustor to detect the instantaneous droplet distribution and its behavior. Mie scattering theory is applied to the conventional Particle Image Velocimetry and the technique enables us to detect the instantaneous planar droplet velocity and size information. This M-PIV technique was evaluated with a generally used indus...

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...
