Abstract
A parallel flow-solver, ParNASSD1, has been developed at LTH2 for simulations of compressible flows in aeronautical and complex industrial applications. The Large Eddy Simulation (LES) technique is used to simulate turbulent flows. The code employs an efficient algorithm, based on the Residual Distribution Scheme approach, well suited for parallelization. It has been implemented in the SPMD paradigm, and uses the PVM defacto standard for message passing.
The ParNAS3D solver has been coupled with an independent spray-module, for LES of spray in compressible flows. This was also done using the PVM message passing system.
The combined LES-spray code has been used to investigate the injection, mixing and evaporation processes of a fuel spray in a gas turbine engine. The code proved to have an excellent scalability, both when running with and without the spray module.
This is the first report on the implementation of the ParNAS3D parallel algorithm. We present also the numerical algorithm employed in our code.
