“…Flow simulation based upon multi-block structured flow solvers Boerstoel et al (1989Boerstoel et al ( , 1992 is faster and more efficient in terms of computational time and central memory size, with respect to unstructured solvers. Sliding surfaces coupling is also faster and less demanding with respect to chimera approach.…”

Purpose-Simulate unsteady flows with surfaces in relative motion using a multi-block structured flow solver. Design/methodology/approach-A procedure for simulating unsteady flows with surfaces in relative motion was developed, based upon a structured multi-block U-RANS flow solver1. Meshes produced in zones of the flow field with different rotation speed are connected by sliding boundaries. The procedure developed guarantees that the flux conservation properties of the original scheme are maintained across the sliding boundaries during the rotation at every time step. Findings-The solver turns out to be very efficient, allowing computation in scalar mode with single core processors as well as in parallel. It was tested by simulating the unsteady flow on a prop fan configuration with two counter-rotating rotors. The comparison of results and performances with respect to an existing commercial flow solver (unstructured) are reported. Originality/value-This paper fulfils an identified need to allow for efficient unsteady flow computations (structured solver) with different bodies in relative motion.

Abstract. The aim of this paper is to show a practical experience in parallelizing a large CFD code starting from a sequential version. Major steps developing this activity for a 30000-Fortran-statements code are showed. This is done focusing on difficulties, techniques, "open" problems and solutions that a multidisciplinary group faces during the work. As a case study, the parallel implementation of a 3D Thin Layer NavierStokes code, originally developed in collaboration with Alenia and NLR , for the simulation of the subsonic/transonic flow around a complex aerodynamic configuration is considered. The message passing, for the data transmission among processors, is handled by PVM. The target parallel architectures are several MIMD machines (including cluster of workstations); a comparison of the results, in terms of performance, with the current most powerful supercomputers is presented.
