Parallel NAS3D: An Efficient Algorithm for Engineering Spray Simulations using LES

摘要

A new parallel flow-solver, ParNAS3D, has been developed at Lund Institute of Technology for simulations of compressible flows in aeronautical and complex industrial applications. The code employs an efficient algorithm, based on the Residual Distribution Scheme approach, well suited for parallelization. The ParNAS3D solver has been coupled with an independent spray-module for LES of spray in compressible flows. 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. This is the first report on the implementation of the ParNAS3D parallel algorithm. We present also the numerical algorithm employed in our code.
