..., 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...

... that this will not adversely affect the ability of the accelerated deposition facility to duplicate the deposit mechanisms under study. Seed particle size distribution by mass Seed particles were selected to match the typical particulate size and chemistry found in the atmosphere. Contact with Air Filter Testing...
