CFD models created for blown-powder systems

During MMTECH, the complete process for additively-manufactured γ-TiAl will be modelled. Strathclyde have created a model to simulate powder flow as it is ejected from the nozzle during laser metal deposition has been created and allows substrate rebounds to be considered. The CFD model is a general analysis of powder dynamics and is essential for modelling subsequent processes such as powder fusion and deposited track formation. The next step is to modify it to reflect the specific geometry of the of Laser Engineering Net-Shaping (LENS MR-7) system which is being installed at Sheffield.
