Syngas ash deposition for a three row film cooled leading edge turbine vane
… and high gas stream velocities can cause Deposition, Erosion, and Corrosion (DEC) of turbine components downstream of the combustor section. The objective of this dissertation is to use computational techniques to investigate the dynamics of ash deposition in a leading edge vane geometry …

Simulated Syngas Ash Deposition on the Leading Edge of a Turbine Vane with Film Cooling
In using coal derived syngas in a gas turbine, solid particulates coming out of the gasifier can prove to be detrimental to the engine hardware. Not much is known about particle deposition, erosion, and corrosion on turbine blades as a result of these contaminants. Performing deposition studies at …

Large Eddy Simulation of Leading Edge Film Cooling: Flow Physics, Heat Transfer, and Syngas Ash Deposition
… ratio. The dissertation also investigates the deposition and erosion of Syngas ash particles in the film cooled leading edge region. Three ash particle sizes of 1, 5, and 10 microns are investigated at all blowing ratios using Lagrangian dynamics. The 1 micron particles with momentum Stokes …
