Three-component particle image velocimetry in a generic can-type gas turbine combustor

Can KIVA Accurately Simulate a Gas Turbine Combustor?

KIVA is a widely used (;ode for combustion simulation in engines. We discuss its shortcomings in approximating real gas turbine combustors and what might be done to improve its performance. It is assumed that the combustion and CFD phenomena are modeled with complete accuracy and that the solution of discretized versions of these models is also accurate. Thus the focus is on the geometry, grid ...

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 ...

Characterization of a Dual-Mode Scramjet Combustor via Stereoscopic Particle Image Velocimetry

The following research paper presents an up-to-date status of the testing of a Dual-Mode Scramjet (DMSJ) model which is experimentally operated at UVa’s Aerospace Research Laboratory. The optical technique Stereoscopic Particle Image Velocimetry (SPIV) is applied to the combustor of the DMSJ with a ramp fuel injector configuration. SPIV is utilized to measure the three-dimensional, combusting, ...

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

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...
