Abstract Scope |
Modeling and simulation provide a means of predicting the impact of microstructure on the effective thermal conductivity of a material. Mesoscale heat conduction simulations provide a means of directly representing a microstructure and quantifying its impact on the effective thermal conductivity. However, due to the computational cost of this approach, it cannot be used to predict macroscale thermal performance. To overcome this issue, mesoscale simulation results can be used to inform the development of analytical thermal resistor models that efficiently estimate the effective thermal conductivity. In this presentation, we summarize the mesoscale approach, discuss the need for 3D simulations, and illustrate how the mesoscale results can be used to inform the development of thermal resistor models. We demonstrate the approach using various examples related to nuclear reactor fuel. |
