The contribution of thermal radiation to the thermal conductivity of porous U02

Thermal diffusivity of Americium mononitride from 373 to 1473 K

“…Among a variety of porosity correction formulas, Eq. (3) was in best agreement with the result of the finite element computations in the wide range of the porosity up to 0.3 as reported by Bakker et al [16]. The thermal conductivities of AmN with 77.5%TD and corrected to 100%TD are shown in Fig.…”

Thermal conductivities of (Np,Am)N and (Pu,Am)N solid solutions

“…Among a variety of porosity correction formulas, the equation (12) was in the best agreement with the result of the finite element computations in the wide range of the porosity up to 0.3 as reported by Bakker et al [18]. The thermal conductivities of (Np,Am)N and (Pu,Am)N solid solutions corrected to 100%TD in the temperature range between 473 and 1073 K are shown in figure 5, together with those of NpN [5], PuN [3] and AmN [5].…”

Distributed Porosity as a Control Parameter for Oxide Thermal Barriers Made by Physical Vapor Deposition

“…Also plotted on Fig. 3(a) is the numerical result for spheres placed in a simple cubic array, 28 illustrating the similarity with the analytical result. When the conductivity of the gas phase is significant, the full solution of Eq.…”

“…11 Based upon both the comparisons shown on Fig. 3 28 and the conclusions of Kachanov et al, 11 the noninteracting scheme is taken as a simple and, yet, reasonably accurate method suitable for performing assessments on TBCs. This method is used in Sections IV and V to generate the spectrum of results needed to evaluate the thermal performance of EB-PVD materials and to establish their correlation with elastic properties.…”
