Evolution of Turbine Blade Deposits in an Accelerated Deposition Facility: Roughness and Thermal Analysis
… The deposits were formed using the BYU Turbine Accelerated Deposition Facility (TADF), which was used to simulate three months of deposition within a two hour test time. All three coupons underwent four cycles in the TADF: eight total hours of combustor testing—or one simulated year of …

Particle Size, Gas Temperature, and Impingement Cooling Effects on High Pressure Turbine Deposition in Land Based Gas Turbines from Various Synfuels
Four series of tests were performed in an accelerated deposition test facility to study the independent effects of particle size, gas temperature, and metal temperature on ash deposits from two candidate power turbine synfuels. The facility matches the gas temperature and velocity of modern first …

Experimental Investigation of Microparticle Sand Sticking Probability from 1000°C to 1100°C
… deposits onto a bare surface can determine the accelerated deposition rate depending on subsequent particulate impinging onto the surface. To emulate the initial deposits, a HASTELLOY® X test coupon was exposed to 20 μm to 40 μm samples of Arizona Road Test Dust (ARD) at varying loadings and …

Experimental Investigation of Particulate Deposition on a Simulated Film-Cooled Turbine Vane Pressure Surface in a High Pressure Combustion Facility
… into the high pressure facility to perform accelerated deposition of the fly-ash onto the test articles. A method was developed to process the fly-ash to match the theoretical size distribution and particle flow dynamics representative of an industrial gas turbine scaled. Analyses were …
