Stabilized-® nite-element / interface-capturing technique for parallel computation of unsteady ̄ ows with interfaces q

We present the stabilized-®nite-element/interface-capturing (SFE/IC) method developed for parallel computation of unsteady ̄ow problems with twōuid interfaces and free surfaces. The SFE/IC method involves stabilized formulations, an interface-sharpening technique, and the enforcement of global mass conservation for each ̄uid. The SFE/IC method has been eciently implemented on the CRAY T3E parallel supercomputer. A number of 2D test problems are presented to demonstrate how the SFE/IC method works and the accuracy it attains. We also show how the SFE/IC method can be very e€ectively applied to 3D simulation of challenging ̄ow problems, such as twōuid interfaces in a centrifuge tube and operational stability of a partially ®lled tanker truck driving over a bump.
