Parabola

Coupling Model and Numerical Computation Method of Keyhole and Weld Pool, The discontinuous boundary conditions of thermocapillary force, surface tension and recoil pressure on the interface between keyhole and weld pool are deduced based on incompressible viscous flow assumptions. Numerical implementations of this self-consistent model are also introduced.
