Flow instabilities in liquid metal pools
Research goal
This project is devoted to the stability analysis of fusion welding processes. The primary aim of this research is to construct a novel, physically-based numerical approach for assessing the stability of a melt pool suspended between solid side walls and subject to excitation and variations in orientation and geometric boundary conditions. The proposed approach is envisaged to be applicable to any fusion welding processes, since the process can be defined by a set of boundary conditions and be controlled by introducing perturbation terms to the applied boundary conditions. The overall aim is to get a better insight into weld pool dynamic behaviour.
