CFD-Guided Development of Test Rigs for Studying Erosion and Large-Particle Damage of Thermal Barrier Coatings
Figure 12
Most probable particle trajectories for various injection velocities in an unducted burner rig operated at a Mach number of 0.3 and a single-particle diameter of 26 microns. Note that interior bouncing can result in particles injected at higher velocities tracking toward the upper half of the test specimen, and particles injected at lower velocities can track toward the lower half of the test specimen.
