Abstract: Abstract A numerical method for the direct numerical simulation of incompressible flows with interfaces between two fluids with totally different density and viscosity is developed. The method is applied to binary droplet collisions and to the droplet impact on liquid films. Corresponding simulation running times are reported. The single-processor performance and the parallel performance of the code on NEC SX-4 and Cray T3E/512-900 at HLRS are analyzed. It is concluded, that simulations with this code should be run on the Cray T3E/512-900 only for problems, which are too large for the NEC SX-4.
