| Abstract: | Youngs' VOF (volume of fluid)algorithm is improved using unsplit interface propagation with its formulas deduced. The unsplit algorithm provides better solutions to fluid flow problems with interfaces. Comparison of results for a typical example with interfaces studied numerically using the Donor Acceptor, and split and unsplit Youngs' algorithms indicates that the unsplit Youngs' algorithm guarantees more accurate interface solutions both spatially and temporally, which can trace fluid interfaces more effectively. |
