Abstract
A mathematical model for the simulation of the turbulent reactive flow and heat transfer in a power station boiler has been parallelized. The mathematical model is based on the numerical solution of the governing equations for mass, momentum, energy and transport equations for the scalar quantities. The k-ε model and the conserved scalar/prescribed probability density function formalism are employed. Radiative heat transfer is calculated using the discrete ordinates method. The code has been fully parallelized using the spatial domain decomposition approach and MPI. Calculations were performed using an IBM-SP2. It is shown that the computational requirements are reduced and the parallel efficiency increases if the mean temperature and density are calculated a priori, and stored. The role of the different parts of the code on the parallel performance is discussed. A speedup of 5.9 is achieved using 8 processors.
