Abstract

A steady state model of heat transport by conduction and convection is extended to include both Marangoni and Lorentz effects. Both effects are investigated with respect to heat transport and solidification in a stationary axisymmetric weld pool. The PHOENICS implementations of Marangoni and Lorentz effects are validated against individual analytical solutions. Furthermore, the integration of the effects within the fluid dynamics of an axisymmetric weld pool is compared against available data.
