In the present work, a comparative assessment is presented to establish the accuracy of some algebraic Volume of Fluid (VOF) schemes toward capturing a sharp interface. The comparative assessment is reported here between CICSAM, m-CICSAM, SAISH, and MSTACS through benchmark test cases in two- and three-dimensional domain. It is established through the present analysis that MSTACS exhibits a minimal degree of numerical diffusion compared to other schemes, resulting in precise depiction of sharp interfaces across a broad spectrum of Courant numbers.

摘要

In the present work, a comparative assessment is presented to establish the accuracy of some algebraic Volume of Fluid (VOF) schemes toward capturing a sharp interface. The comparative assessment is reported here between CICSAM, m-CICSAM, SAISH, and MSTACS through benchmark test cases in two- and three-dimensional domain. It is established through the present analysis that MSTACS exhibits a minimal degree of numerical diffusion compared to other schemes, resulting in precise depiction of sharp interfaces across a broad spectrum of Courant numbers.
