Modeling radiation in particle clouds: on the importance of inter-particle radiation for pulverized solid fuel combustion
Abstract The importance of inter-particle radiation for clusters of gray and diffuse particles is investigated. The radiative cooling of each individual particle is found to vary strongly with its position in the cluster, and a “mean” radiative particle cooling term is proposed for single particle s...

520 | |a Abstract The importance of inter-particle radiation for clusters of gray and diffuse particles is investigated. The radiative cooling of each individual particle is found to vary strongly with its position in the cluster, and a “mean” radiative particle cooling term is proposed for single particle simulations of particle clusters or for high detail simulation, like Direct Numerical Simulations of small sub-volumes of large clusters of particles. Radiative cooling is shown to be important both for furnaces for coal gasification and coal combustion. Broadening the particle size distribution is found to have just a minor effect on the radiative particle cooling. This is particularly the case for large and dense particle clusters where there is essentially no effect of size distribution broadening at all. For smaller and more dilute particle clusters, the effect of distribution broadening is clear but still not dominant. | ||

The radiative cooling of each individual particle is found to vary strongly with its position in the cluster, and a “mean” radiative particle cooling term is proposed for single particle simulations of particle clusters or for high detail simulation, like Direct Numerical Simulations of small sub-volumes of large clusters of particles. Radiative cooling is shown to be important both for furnaces for coal gasification and coal combustion. Broadening the particle size distribution is found to have just a minor effect on the radiative particle cooling. This is particularly the case for large and dense particle clusters where there is essentially no effect of size distribution broadening at all.

The radiative cooling of each individual particle is found to vary strongly with its position in the cluster, and a “mean” radiative particle cooling term is proposed for single particle simulations of particle clusters or for high detail simulation, like Direct Numerical Simulations of small sub-volumes of large clusters of particles. Radiative cooling is shown to be important both for furnaces for coal gasification and coal combustion. Broadening the particle size distribution is found to have just a minor effect on the radiative particle cooling. This is particularly the case for large and dense particle clusters where there is essentially no effect of size distribution broadening at all. For smaller and more dilute particle clusters, the effect of distribution broadening is clear but still not dominant.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Direct Numerical Simulation</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Radiative Flux</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Radiative Cool</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Particle Cluster</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Particle Number Density</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Mitchell, Reginald E.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Heat and mass transfer</subfield><subfield code="d">Springer Berlin Heidelberg, 1968</subfield><subfield code="g">51(2014), 7 vom: 16.

Modeling radiation in particle clouds: on the importance of inter-particle radiation for pulverized solid fuel combustion |
abstract |
Abstract The importance of inter-particle radiation for clusters of gray and diffuse particles is investigated. The radiative cooling of each individual particle is found to vary strongly with its position in the cluster, and a “mean” radiative particle cooling term is proposed for single particle simulations of particle clusters or for high detail simulation, like Direct Numerical Simulations of small sub-volumes of large clusters of particles. Radiative cooling is shown to be important both for furnaces for coal gasification and coal combustion. Broadening the particle size distribution is found to have just a minor effect on the radiative particle cooling. This is particularly the case for large and dense particle clusters where there is essentially no effect of size distribution broadening at all. For smaller and more dilute particle clusters, the effect of distribution broadening is clear but still not dominant. © Springer-Verlag Berlin Heidelberg 2014 |
