About This Lesson
- In the Laser Cladding project, we simulated the deposition of nickel droplets under an argon gas stream using ANSYS Fluent software.
- The three-dimensional geometry was created in Design Modeler with a computational domain of 0.05 × 0.01 × 0.025 m. A structured non-conformal mesh was generated in ANSYS Meshing, consisting of approximately 798,400 computational cells with refined regions near the deposition zone.
- The transient simulation employed the VOF multiphase model, coupled with species transport and energy equations, while turbulence was modeled using the Realizable k-ε model.
- A User-Defined Function (UDF) implemented the moving Gaussian laser heat source, enabling realistic simulation of droplet injection, spreading, and weld layer formation.
