Abstract

"The first part of the thesis aims to understand the flow structure of coaxial nozzle used in laser aided material deposition process and be able to control focused particle stream by switching shielding gas ratio and outer shielding gas inclination angle...The second part proposes a stochastic model, which considers particle shape effects, to quickly simulate realistic powder flow and also meet the practical requirement for design optimization of the coaxial nozzle."--Abstract, page iv.
