“…Silicon carbide and zirconia particles are simulated separately, their properties at high temperatures are shown in Table 1 (Incropera et al, 2013,Modest, 2013,Geldart, 1986,Verein, 2010. The emissivity data provided in (Mullinger and Jenkins, 2008) is used to consider the temperature effect on the particle emissivity during the simulations. Following the experiments reported in (Flamant, 1982), air enters at 20ºC to a bed initially at 20ºC.…”
