Abstract

A Lagrangian particle tracking model is applied to the simulation of the discrete phase in coal-fired furnaces. The interaction of particles with the gas phase leads to additional source terms in the Eulerian transport equations of mass, momentum and enthalpy. The radiative heat exchange of the particles is directly coupled with the discrete ordinates method using an extra source term in the discre- tised radiative transport equation. The routines for the particle model are vectorised using loops over the number of all particles. They are implemented in the 3D combustion code AIOLOS, optimised for vector and parallel computers to achieve high numerical efficiency. The code is applied to the numerical simulation of a utility boiler, showing a high performance and vectorisation rate, combined with good agreement with measurements.
