Abstract
A code for the simulation of the turbulent reactive flow with heat transfer in a utility boiler has been parallelized using MPI. This paper reports a comparison of the parallel efficiency of the code using the hybrid central differences/upwind and the MUSCL schemes for the discretization of the convective terms of the governing equations. The results were obtained using a Cray T3D and a number of processors in the range 1 – 128. It is shown that higher efficiencies are obtained using the MUSCL scheme and that the least efficient tasks are the solution of the pressure correction equation and the radiative heat transfer calculation.
