As is has been discussed in the previous topic (https://www.cfdem.com/forums/radiation-model-can-be-added-packed-bed)
My new paper on the paritcle thermal radiation is published in the Journal of Heat Transfer (ASME),the titile is "Modelling effective thermal conductivity (ETC) of thermal radiation for nuclear packed pebble beds",
the link is http://heattransfer.asmedigitalcollection.asme.org/article.aspx?articlei...
Any more idea on the paritcle thermal radiation is welcomed !
