Onset of Arizona Road Dust in High Temperature Environment on a Cooled HASTELLOY X Surface
… there has been an increased interest in sand, dust, and ash particulates ingestion study for gas turbine engine applications. Recently, there has been an increase in commercial and military fleets operating in medium to highly dusty environments, such as areas in Africa, the Middle East, and …

Effect of Temperature on Microparticle Rebound Characteristics at Constant Impact Velocity
… taken using the Virginia Tech Aerothermal Rig. Arizona Road Dust (ARD) of 20-40 μm is injected into a flow field to measure the effects of temperature and velocity on particle rebound from a polished high temperature material coupon. The high temperature coupon was tested at different …

Experimental Investigation of Initial Onset of Sand Deposition in the Turbine Section of Gas Turbines
… section. The experiments are performed using Arizona Road Dust (ARD) of 20-40 μm size range. The temperature of air and particles are around 1100°C at a constant velocity of 70 m/s. The target coupon is made of Hastelloy X, a nickel-based alloy and the angle at which the particles impact the …

Technique for Measuring the Coefficient of Restitution for Microparticle Sand Impacts at High Temperature for Turbomachinery Applications
… of sand at different impact angles. Two sizes of Arizona Road Dust (ARD) and one size of Glass beads are impacted on to 304-Stainless Steel. The particles are entrained into a free jet of 27m/s at room temperature. Mean results compare favorably with trends established in literature. This …

Measurement Drift in 3-Hole Yaw Pressure Probes From 5 Micron Sand Fouling at 1050° C
… environments of 1050 C at 65-70 m/s. 0-5 micron Arizona Road Dust(ARD) is heated under these conditions and used to foul the yaw probes. The sand deposited on the probe was observed to peel off the probe in thin sheets during ambient cool down. Sand fouling was assessed using a stereoscope and …

Experimental Investigations of the Onset of Sand Deposits on Hastelloy-X between 1000 C and 1100 C
… to quantitatively characterize the deposition of Arizona Test Dust (ATD) onto Hastelloy X. The first study presented in this thesis describes a preliminary investigation of sand deposition at temperatures and velocities similar to those found in the turbine section of propulsive gas turbine …

Experimental Investigation of Microparticle Sand Sticking Probability from 1000°C to 1100°C
… are increasing the likelihood of sand and dust ingestion. Turbine engines are particularly susceptible to the ingestion of sand and dust, which can erode cold-section components and deposit onto hot-section components. Ultimately, the erosion and deposits will shorten the operational …

Experimental Investigation of Temperature Effects on Microparticle Sand Rebound Characteristics at Gas Turbine Representative Conditions
… manner. The COR data for two different sizes of Arizona Road Dust (ARD) and one size of glass beads are presented in this paper. Target material was stainless steel 304 and the impact angle was varied from 25 to 85 degrees. The second study details the first quantification of the COR of san …
