Efficient Parallel Implementation of a Hybrid Finite Volume/Particle Method for the PDF Equations of Turbulent Reactive Flows
Abstract
Turbulent reacting flows are of great importance in modern society and occur frequently, for example, in internal combustion engines, gas turbines, furnaces etc. The computational modelling of turbulent reacting flows is widely used to aid understanding and control turbulent flames, to improve efficiency, and to reduce pollutant emissions, reduce design costs and development times. However, turbulent combustion remains one of the most complicated phenomena to describe and simulate using numerical tools. In this paper, an efficient parallel implementation of the hybrid finite-volume/particle method for the PDF equations of the turbulent reactive flows is introduced. A method called domain partitioning of particles is implemented. The code has been tested by using a non-reacting case of the vitiated coflow combustor. Results about the speed-up performance in this test case are shown. Since in PDF/Monte Carlo methods the particle properties are advanced independently in time, the speed-up performance of this code for the particle part is very close to ideal. Finally, the speed-up performance with detailed chemistry calculation is analyzed.
