Parallelisation of the discrete transfer radiation model

Parallelisation of the discrete transfer radiation model
Parallelisation of the discrete transfer radiation model
The transfer of energy by thermal radiation represents an important component in many reacting flows. Thus, when radiative energy exchange is included in a complete, parallel CFD simulation of such systems, the relatively large computational expense of evaluating this complex process demands efficient parallelisation of the radiation sub-model. This article investigates the parallelisation of the discrete transfer radiation model, paying particular attention to different solutions to the radiative transfer equation. Speed-up efficiencies of a constant absorption coefficient solution, a weighted sum of gray gases solution, and a differential total absorptivity solution are compared across a non-uniform mixture of combustion gases and soot.

Abstract

The transfer of energy by thermal radiation represents an important component in many reacting flows. Thus, when radiative energy exchange is included in a complete, parallel CFD simulation of such systems, the relatively large computational expense of evaluating this complex process demands efficient parallelisation of the radiation sub-model. This article investigates the parallelisation of the discrete transfer radiation model, paying particular attention to different solutions to the radiative transfer equation. Speed-up efficiencies of a constant absorption coefficient solution, a weighted sum of gray gases solution, and a differential total absorptivity solution are compared across a non-uniform mixture of combustion gases and soot.
