Visualization of the powder gas interactions
How does the powder dynamic influence the DED-LB/M process?
Challenge and Motivation
- Previous project shows: the formation of powder gas flow varies is significantly depending on the nozzle design.
- Interaction of powder particles and gas stream is not depictable through high speed and layer-by-layer analysis.
- Visualization can facilitate application-based process optimization.
Objective
- Use combined high speed in situ Shadowgraph and Schlieren Imaging to visualize shielding gas flow and powder dynamics post- and in process
