..., 0.8, and 1.2. Ash particle sizes of 1 μ m , 3 μ m , 5 μ m , 7 μ m , and 10 μ m are investigated using Lagrangian dynamics. The 1 μ m particles with momentum Stokes number, St p = 0.03 (based on approach velocity and leading edge diameter), follow the flow streamlines around the leading edge and few...

... roughness. The measurements indicate that both erosion and surface roughness increase with impact angle and particle size. Computational results are presented for the particle trajectories through the first stage of a low-pressure turbine of a high bypass turbofan engine. The trajectories indicate...
