A 3-D CFD flow code for multi-stage turbomachinery flow computation, namely the Dawes code ‘un_b3d_ke’ has been parallelized on the NAL Flosolver parallel computer Mk5 using MPI libraries. The parallelization has been effected employing very basic MPI subroutines. The parallel code performance has been tested for a high pressure ratio fan stage and a 3-stage compressor flow simulations and the results have been compared with the sequential code results. It is found that the time taken by the parallel code for the computation is substantially reduced
