Multiple-fluid simulation has received increased attention from the
graphics community in the past few years. Multiple-phase or
multiple-component fluid simulations are crucial to reproduce realistic
visual effects from a wide range of real-world phenomena,
which are not adequately modeled by single-phase approaches. Previous
works on multiple-fluid simulation can be divided into two
main categories focusing on either immiscible fluids or on miscible
or dispersed fluids. In the former category, clear interfaces exist
between different phases, and many works (e.g., [Hong and Kim
2005; Losasso et al. 2006; Kim 2010; Boyd and Bridson 2012;
Misztal et al. 2012; Da et al. 2014]) have obtained visually plausible
results by tracking the interfaces. However, in the latter category,
there are no clear interfaces between different phases, and
the volume fraction method [Muller et al. 2005 ¨ ] has been widely
adopted.
