Computation Efficiency of S-CLSVOF Method for Additive Manufacturing Applications
The S-CLSVOF method is extended for direct numerical simulation in additive manufacturing applications. It is implemented in the framework of the OpenFOAM® and is appended by thermocapillary force and the energy equation. A number of 2D test cases are used for the verification which involves modeling of a stationary isothermal droplet, the Marangoni-driven flows in a rectangular cavity and the two-phase free surface Marangoni-driven flows. The tests are designed to verify the phenomena peculiar to additive manufacturing applications. It is shown that having a special treatment method could get the accurate results in a reasonable time.
