| Description |
A three-dimensional lattice Boltzmann (LB) scheme is presented in this article to address the incompressible transport
phenomena in the presence of a continuously evolving phase change interface typically encountered in high-energy
materials processing applications. The proposed LB scheme utilizes three separate distribution functions to monitor the
underlying hydrodynamic, thermal, and compositional fields. Accordingly, the kinematic viscosity, and thermal and
mass diffusivities can be adjusted independently, which makes the model suitable for a wide range of phase change
problems in high-power materials processing applications. The phase-changing aspects are incorporated into the LB
model by inserting appropriate source terms in the respective kinetic equations through the most formal technique—following the extended Boltzmann equations along with an adapted enthalpy updating scheme in association with
the classical enthalpy-porosity technique for solid–liquid phase transition problems. The model is used to simulate a
conventional high-power laser surface alloying process and excellent agreement with the available experimental results
is observed.
