Summary

For enhancing coating quality, the shock tunnel technology is employed to achieve impact velocities of particles up to 1500 m/s for 10 μm solid particles. A calibration of the nozzle flow has been carried out by using a Pitot rake. The current conditions in the reservoir achieved so far are p 0=140 bar and T 0 = 1800 K. A high speed schlieren system is set up for flow visualization and also for velocity measurement of visible particles. For fine particles, both LDA and PIV methods are used for particle velocity measurements. The achieved results are in good agreement with a quasi-1D prediction.
