“…In the current method, these modes are damped through the use of iterated projection and velocity filters as discussed by Rider (1994). The MPFA, discussed in the previous paragraphs, has been shown to be an accurate, robust method of high fidelity (Rider et al, 1995). It has been used to solve constant density flow problems (Bell, Colella and Glaz, 1989), and has been extended to the variable density case (Bell and Marcus, 1992 , 1997), to solve two-phase flow problems.…”
