Abstract: Abstract Recent applications in the field of computational fluid dynamics are presented, which were run on the NEC SX-4 of the High-Performance Computing Center of Stuttgart. External and internal flow problems were simulated. The internal flow problems include the breakdown of a slender vortex in a pipe flow and the flow in a piston engine during the intake and compression stroke. In addition, large-eddy simulations of turbulent flow through pipe bends and of turbulent jet flows are presented. All results are obtained with explicit or implicit solution schemes on block structured curvilinear grids. The number of grid points varies from 300,000 in the case of a turbulent jet to approx. 2 million in the case of the piston engine flow. All algorithms are vectorized and parallelized. Characteristic computing times and memory requirements are reported for the different applications.
